Thipsamai

Pad thai was a state project, promoted nationwide by Field Marshal Plaek Phibunsongkhram's government in the 1940s, and Thipsamai grew up beside the campaign: founder Samai sold noodles from a boat on the Phasi Charoen canal during World War II, set up at the Pratu Phi intersection, and registered the name on September 9, 1966. The house account says Phibun himself praised it as "the true and authentic taste of PADTHAI."

Why go

The house claims two firsts, Bangkok's first dedicated pad thai stall and "the first one creating Padthai Sen-Chan with shrimp oil and prawns wrapped in egg" (venue history; no independent confirmation located). The mechanics justify the trip regardless of who was first: sun-dried sen chan rice noodles fried hard over charcoal, then dressed with an oil rendered from shrimp-head tomalley, the same fat that makes lobster bisque taste of more than shellfish meat. A Michelin Bib Gourmand puts it in the guide's value tier, and BK Magazine calls it "one of the best pad Thai joints in the city."

Order this / avoid

• Order: the pad thai haw kai with shrimp oil, Jeff's order, which BK Magazine rates the "to-die-for pad Thai hor khai goong (shrimp pad Thai wrapped in a thin egg crepe)." Cut the richness with the fresh-squeezed orange juice from the front stall, famous enough that Jay Fai's staff specifically ban customers from carrying it in next door (Time Out).
• Avoid: the basic plate when the shrimp-oil version is the reason to come, and trusting the closed day without checking: the venue site says closed Tuesday while BK's review listed it closed Monday, so glance at Maps the morning of.

What locals & experts say

• BK Magazine: "One of the best pad Thai joints in the city," and "always busy so expect to wait for a table during prime dinner hours." ref
• Michelin Guide Thailand: Bib Gourmand; the 2026 Bib selection runs 137 venues with 44 in Bangkok and surrounds. ref
• Thipsamai (house history): "the true and authentic taste of PADTHAI," the praise it attributes to PM Phibunsongkhram. ref

Good to know

• Timing: 9am to midnight per the venue site, with the closed-day conflict above; the line peaks with the dinner crowd, so mid-afternoon is the quiet window.
• Booking: none; the queue moves fast because the woks do.
• Getting there: Maha Chai Road at the Pratu Phi intersection, on the same block as Jay Fai; one walk covers Bangkok's two most famous street-food rooms. Mall branches trade on the name, and the shophouse here is the original.

Jeff's take (his words)

• Note: most famous phat thai; get with shrimp oil.

Verdict (Chef Jeff ladder)

should-visit — The reference version of Thailand's national dish, from the stall that claims its shrimp-oil, egg-wrapped form, cooking over charcoal at the same gate since the 1940s with a Michelin Bib Gourmand and street prices. It stops short of must-visit because the dish, unlike Jay Fai's omelette, has credible rivals across the city and the queue is a real cost against a sub-B300 plate. Pair it with Jay Fai on the same block and the detour pays twice.
