Koya Soho

The udon and the dashi are made from scratch every morning, and the bowl a critic called one of the great modern London dishes is a full English cooked into it.

Why go

Koya opened on Frith Street in 2010 and the venue's own description of itself has barely moved since: "freshly made udon noodles and dashi with simple, paired back interiors", head chef Shuko's cooking running "from breakfast through to dinner" (Koya). Twenty-five stools face the kitchen, there are no bookings, and they seat complete parties only. The Good Food Guide's read on why it works is technical rather than romantic: the noodles have "just the right bite and mouthfeel, smooth, silky and bouncy, with added oomph from the quality of the kake (dashi and mirin broth)" (Good Food Guide). Sixteen years on, a working chef still names it as her solo default and an industry poll still ranks it fourth for breakfast in London. That is the institution test passed on current evidence rather than on age.

Order this / avoid

• Order: the English Breakfast Udon, which Jake Missing called "truly one of the great modern London dishes." ref Otherwise atsu-atsu for hot noodles in hot broth, hiya-hiya for cold with a dipping sauce, and tenzaru or niku on top.
• Avoid: arriving as a group in pieces. They seat you when everyone is there.

What locals & experts say

• Jemma Harrison, chef at Kaunter, in la grappe's chef-haunts piece, February 2026: "Is my absolute go to, particularly if I'm dining solo. I sit at the bar and slurp udon and munch tempura. It feels like a home away from home." ref
• TOPJAW's aggregate breakfast poll (April 2025), Koya at No. 4, drawn from their own two hundred-odd industry interviews: "the beautifully niche Koya. Koya got huge respect straight out of the gate because of their commitment to being very authentic and hand making udon noodles. Which is why they're loved by chefs, industry folk, Japanese people." ref
• Jake Missing, The Infatuation (September 2023), 8.7/10, on the value: "brilliant, innovative bowls for under GBP 20," in what he calls a "knowingly transient place". ref
• The Good Food Guide, band Good, on the room and the crowd: "Pared-back decor, counter seating, no bookings and regular queues at busy times," where people come "to just slurp and go". ref

Good to know

• Where: 50 Frith Street, W1D 4SQ, in the middle of Soho.
• Sites: three Koya restaurants, plus a railway arch in Hackney that looks like production. This row is the Soho original; the others are Koya City at Bloomberg Arcade and Koya Ko at Broadway Market Mews. A review of one is not a review of another, and the Frith Street counter is the one every source here ate at.
• Booking: none taken. Queues at busy times, and complete parties only.
• Timing: all day, seven days, breakfast through dinner, closing at 10pm. Missing's advice is to come about an hour before that, or to come for breakfast.
• Hygiene: FSA rating 5, Westminster, inspected 2 September 2024. The register files this address under the name "Koya-Ko", which is also what the separate Broadway Market site is called; they are different premises with different FHRSIDs. ref

Jeff's take (his words)

Jeff saved Koya Soho with no note. His raw saved-places export carries an empty Note for this row, so nothing above is in his voice and no order is attributed to him.

Verdict (Chef Jeff ladder)

must-visit — Build a morning around it. The udon and the dashi are made from scratch every day at a twenty-five-stool counter that has been on Frith Street since 2010, and the room still gets it right sixteen years in. Jake Missing scored it 8.7 and called the English Breakfast Udon 'truly one of the great modern London dishes', which is a career-dish claim about a bowl that costs less than twenty pounds. Jemma Harrison, who cooks at Kaunter, says it is her 'absolute go to, particularly if I'm dining solo. I sit at the bar and slurp udon and munch tempura.' TOPJAW's own poll of two hundred industry interviews put it fourth for breakfast in London. The Good Food Guide's line on the noodles is the technical one that matters: 'just the right bite and mouthfeel, smooth, silky and bouncy.' Walk in, take a stool, eat in half an hour, and go at breakfast rather than at seven.
