Walthamstow

Weekend pop-up inside the Blackhorse Lane jeans atelier

Jeff's note

SlowBurn

The restaurant only exists at weekends, because Monday to Friday the room is a working denim factory and the tables are in storage (Waltham Forest Guardian).

Why go

Chavdar Todorov started SlowBurn in November 2020, delivering food around E17 on a motorbike during lockdown, and he now cooks out of the kitchen at the back of Blackhorse Lane Ateliers (The Nudge). The atelier makes selvedge jeans all week. At about 4pm on a Friday the machines stop, the tables come out, and roughly 25 to 30 covers get set up between the workbenches (City AM).

Vegetables lead and meat plays a supporting part, which the Good Food Guide read as "a good-value, vegetable-led menu tuned to the seasons" (Good Food Guide). You can watch that rotation happen: of everything City AM ate in July 2023 and everything Time Out ate in November 2025, one dish appears on both lists.

The buying is specific. Fosse Meadows free-range chicken, St Austell bay mussels, Pitchfork cheddar, Wild Grains sourdough. Todorov gives the chicken a spicy rub and smokes it, and gives the roast baby potatoes the same treatment.

Order this / avoid

  • Order: the black bean gyoza tacos, which have run since the first week, and the smoked chicken by the quarter if you are sharing widely. Charred sweet potato on cavolo nero chimichurri, and whichever brassica is in, because that is where the seasonal cooking shows.
  • Avoid: the octopus, marked down as overcooked inside a four-star review. Any plan that involves eating here on a weekday.

What locals & experts say

  • Leonie Cooper, Time Out London, November 2025, 4 out of 5 and Recommended: "This isn't tweezer-tastic fine dining, but great, semi-chaotic things on a plate that comfort and coddle as well as surprise and shock." She also wrote the sentence this entry treats as the honest caveat: "a somewhat overcooked octopus with pak choi". ref
  • Steve Dinneen, City AM, July 2023: "There's some really, really great cooking on display at SlowBurn, unflashy and without frills, as you would expect of a kitchen borrowed from an atelier." His dish of the night was "lamb shoulder in a sea of neon green: peas, kohlrabi, confit shallots and wild garlic. A real belter of a dish." ref
  • The Good Food Guide, Britain's 100 Best Local Restaurants 2025: "Depth of flavour and proper savouriness are chef/owner Chavdar Todorov's calling cards", and the smoked chicken was "almost impossibly moist and definitely worthy of the name". The review carries no byline, so this is the Guide's verdict rather than a critic's. ref
  • No industry vote. None of the 589 London picks in our chef-vote file names SlowBurn, which is worth saying plainly about a restaurant this well reviewed.

Good to know

  • Where: 114b Blackhorse Lane, Walthamstow E17 6AA. Blackhorse Road station, then a walk past warehouses. Diners regularly spend five to ten minutes finding the door.
  • Timing: Friday evening, then lunch and dinner on Saturday and Sunday. Closed Monday to Thursday.
  • Booking: essential, through the site. City AM's line in 2023 was "getting a table is difficult, book in advance", and the room has not got bigger since.
  • Value: the lunchtime spread runs GBP 26 a head, and there are by-the-glass wines under GBP 10.
  • Dietary: the venue says "most of our dishes are vegetarian and vegan-friendly". It makes no gluten-free or celiac claim, so treat that as unknown.
  • Drink: a short wine list, spritzes and cocktails. Nobody comes here for the bar.
  • Hygiene: FSA rating 5, Waltham Forest, inspected 19 September 2025, FHRSID 1300836.
  • Sites: one. A different pop-up, Denim N' Dine, used this address back in 2016 under another chef; no connection.

Jeff's take (his words)

  • Note: none. His saved-places export carries an empty note against this row, so nothing is put in his mouth. The master CSV line "Weekend pop-up inside the Blackhorse Lane jeans atelier" is enrichment text from an earlier pass, and it is accurate.

Verdict (Chef Jeff ladder)

should-visit — Worth rearranging a weekend for, and it has to be a weekend. SlowBurn cooks out of the kitchen at the back of Blackhorse Lane Ateliers, a working denim factory, and it only opens once the sewing stops on Friday afternoon. Chavdar Todorov has run it since November 2020, when it was a lockdown takeaway he delivered by motorbike, and the cooking now is vegetable-first with meat in a supporting role: black bean tacos built on crisp gyoza skins, charred sweet potato under cavolo nero chimichurri, a spice-rubbed smoked chicken the Good Food Guide called 'almost impossibly moist'. Leonie Cooper gave it four stars in Time Out and Steve Dinneen called the cooking 'really, really great' in City AM, and the Guide put it in Britain's 100 Best Local Restaurants for 2025. It stops short of the top rung for two reasons stated in the evidence itself: the same four-star review marks an overcooked octopus, and there is no dish here you could not eat somewhere else in London. What you cannot get elsewhere is this room, and the room is weighed after the plate.

Order

  • Black bean gyoza tacos, crisp gyoza skins instead of a shell, with a coriander salsa that has been on since the first week
  • The smoked Fosse Meadows chicken, spice-rubbed and cooked so it stays wet, ordered by the quarter, half or whole
  • Sweet potato charred until it goes chewy, under a cavolo nero chimichurri
  • Purple sprouting broccoli in a red curry sauce with peanuts, when the season is on
  • The rosti under ox cheek and tail, which is more meat than potato

Good to know

  • Booking: essential
  • Timing: weekends-only, lunch-only, dinner-only, bookings-essential
  • Best for: dinner, lunch, date, groups-ok, solo
  • Avoid: The octopus. A four-star review still called it overcooked; Turning up Monday to Thursday. The factory works those days and the tables are in storage; Walking in without a table. There are only about 25 to 30 covers and they go
  • Expert picks: Leonie Cooper, Steve Dinneen
  • Dietary: vegetarian-friendly, vegan-options (per venue statements; confirm for medical needs)

    Time Out London (Leonie Cooper, 17 November 2025)

    RATED REVIEW, bylined by Time Out London's Food & Drink Editor. 4 out of 5 stars, tagged Recommended, price 2 of 4, filed under Contemporary Global. Verbatim on the format: 'Slowburn almost isn't a restaurant, it's a slap-up dinner party in a working denim factory. The best seat in the house is next to a gigantic industrial washing machine, scrappy paper patterns for jeans line the walls and there's a lingering smell of starch in the air.' On the founding: 'Chef and founder Chavdar Todorov started Slowburn in late 2020, delivering local meals during lockdown on his motorbike.' On the cooking: 'This isn't tweezer-tastic fine dining, but great, semi-chaotic things on a plate that comfort and coddle as well as surprise and shock.' Dishes named: black bean tacos made with crispy gyoza skins and a coriander salsa, purple sprouting broccoli with a red curry sauce and peanuts, Pitchfork cheddar and brown butter agnolotti, charred sweet potato on cavolo nero chimichurri, a rosti topped with ox cheek and tail 'more meat than it is potato', venison haunch with cranberry and ancho salsa, cured trout in leche de tigre. THE CRITICAL LINE: 'a somewhat overcooked octopus with pak choi'. Practical: 'Slowburn is only open Friday-Sunday'; the lunchtime spread is GBP 26 a head. Closing verdict: 'There's a lot to love about the ever-so-slightly unhinged Slowburn, book in for your very own factory reset.'

    The Good Food Guide (venue review; Britain's 100 Best Local Restaurants 2025)

    AWARD BODY AND GUIDE REVIEW, unbylined so no expert tag. Verbatim: 'Fitting seamlessly inside London's only craft jean makers on Blackhorse Lane, Slowburn turns a working industrial backdrop into something quite informal and quite fetching.' The craft-axis line this entry rests on: 'the kitchen backs up its promise with a good-value, vegetable-led menu tuned to the seasons. When we visited it was heralding the arrival of autumn while retaining some fresher ideas reflecting the warmer weather.' On the chef: 'Depth of flavour and proper savouriness are chef/owner Chavdar Todorov's calling cards, from confit artichoke flower with romesco sauce or black-bean gyoza tacos fired up with a zippy coriander salsa to a main course of Slowburn smoked chicken that was almost impossibly moist and definitely worthy of the name, thanks to a special spicy rub.' Also: roast baby potatoes given the same rub, broccoli with peanut, sweet chilli and mustard, apple tarte tatin, and 'useful by-the-glass options for under GBP 10'. Address 114b Blackhorse Lane, E17 6AA

    City AM (Steve Dinneen, 5 July 2023)

    BYLINED REVIEW by City AM's Life & Style Editor, and the earliest critical read this pass reached. On the room: 'You're flanked on either side by workbenches stacked high with cuts of denim.' On scale and booking: 'There are only a few tables, perhaps enough for 25 or 30 covers (getting a table is difficult, book in advance).' On the food: 'lamb shoulder in a sea of neon green: peas, kohlrabi, confit shallots and wild garlic. A real belter of a dish.' And the verdict: 'There's some really, really great cooking on display at SlowBurn, unflashy and without frills, as you would expect of a kitchen borrowed from an atelier.' Dinneen also flagged a miss in 2023: 'Black bean gyoza tacos lacked the punch to really register.' Address and phone confirmed here: 114b Blackhorse Lane, Walthamstow, E17 6AA. NOTE the 2023 menu and the 2025 menu share only the tacos, which is the evidence for seasonal rotation

    The Nudge (Immy Smith, 18 March 2026)

    The most recent review reached, and the source of the founding date. Verbatim: 'Launched in November 2020 by Bulgarian-born chef Chavdar Todorov, SlowBurn began humbly doing takeaways, lest we forget the absurd restrictions around eating out in restaurants during the various lockdown.' On the day-one dish: Todorov's black bean gyoza tacos 'have been on the menu since day one'. Prices named: a quarter of the smoked Fosse Meadows chicken at GBP 14, veg dishes at GBP 15 and under, salted caramel ice cream at GBP 4. Also names steamed St Austell bay mussels in massaman sauce and whole Cornish sole with caper and parsley beurre noisette. Confirms current trading and the Friday-to-Sunday pattern

    SlowBurn (venue site, read 30 July 2026)

    FIRST-PARTY, facts only. Hours: Friday 5.30pm to 10pm; Saturday 12pm to 3pm and 5pm to 10pm; Sunday 12pm to 3.30pm and 5.30pm to 9.30pm. Booking runs through SevenRooms. Address 114b Blackhorse Lane, Walthamstow, London E17 6AA. The dietary statement this entry's flags rest on, verbatim: 'Most of our dishes are vegetarian and vegan-friendly. More vegetables, more nutrition, less waste.' Positioning, in the venue's own words: 'We want people to take their time, to eat better food, and to live with sustainability in mind.' And on the chef: 'Founder and Head Chef Chavdar Todorov combines a variety of cuisines and concepts that reflect his cosmopolitan and philosophical approach towards food and life.'

    Waltham Forest Guardian (Charlotte Anderson, 22 July 2025)

    LOCAL PAPER, announcement kind, and the provenance for the award plus the chef in his own words. 'SlowBurn, in Blackhorse Lane, has been named as one of Britain's best local restaurants in 2025 by the Good Food Guide.' Todorov: 'We were a little surprised but very proud as well at the same time. This recognition, as well as from the Guide, is also from the people that come and dine with us.' The operating constraint, stated plainly: 'The restaurant is only open between Friday and Sunday, due to Blackhorse Lane Ateliers operating during the week, and the dining tables are only brought out once the factory closes at around 4pm on Fridays.' Team of about 15

    Food Standards Agency (register read 30 July 2026)

    Registered as SLOW BURN, Part A Dowsett House, 114 Blackhorse Lane, Walthamstow E17 6AA, Waltham Forest, FHRSID 1300836. FOOD HYGIENE RATING 5, rating date 19 September 2025. Far above ADR-0022's 0-1 removal trigger, and a September 2025 inspection is itself a live-trading signal. ACCESS NOTE: a name search on 'SlowBurn' returns nothing, because the register spells it as two words; the postcode search on E17 6AA found it. An address search on '114b Blackhorse Lane' also returns nothing, because the register records the premises as Part A Dowsett House

    Time Out London, 'Denim N' Dine' listing (22 September 2016)

    RECORDED AS A REJECTION so the next pass does not conflate them. A ticketed pop-up by chef Pedro Passinhas at 'Blackhorse Lane Atelier, 114b Blackhorse Lane, E17 6AA', running Thursday to Sunday in 2016 with a shared table and an open kitchen. Same address, different operator, four years before SlowBurn existed. None of its evidence is used here
