Ask anyone on the Thonburi side of the river where to get plump egg crab and fat river prawns without driving all the way to Mahachai, and plenty will point you to "Kin Kub Koi" on Phutthamonthon Sai 2 Road. The restaurant belongs to "Jae Koi," whose family ran a seafood wholesale business in Mahachai — and that's the whole story of why this place works. Crab, prawns, fish, all of it comes straight from their own wholesale supply chain daily, so prices land noticeably lower than seafood restaurants in town. The shop originally operated in Samut Sakhon, but that original branch has now closed permanently, and the business has settled at this one spot on Phutthamonthon Sai 2. It's also the location that's earned a Bib Gourmand year after year through 2026, plus a Wongnai Users' Choice award on top — the whole formula behind Bib Gourmand is genuinely good food at a price you don't have to think twice about, and a restaurant with its own supply line pulls that off better than most.
The dish everyone talks about most is the steamed egg crab with fresh milk, priced around THB 720 — a crab shell packed full of roe, with the rich fragrance of fresh milk running through it, the kind of dish that gets people to drive across town. Next up is the salt-fried river prawns, priced by weight, giant and glistening in a way only a wholesaler-run kitchen would dare serve. The tangy steamed sea bass with lime and the squid stir-fried with salted egg are the standing orders that show up at nearly every table, and don't forget the crab fried rice mash, a dish that piles crab meat into rice without holding back. Go with a group and per-person budget starts around THB 250 (that's about what the fried prawn cakes run) and climbs into four figures if you go all out on egg crab and river prawns. The place itself is spacious, with seating split across four zones, and tables turn over fairly quickly — good for a family meal where the whole household shows up together.
One thing worth knowing before you go: the restaurant is firm that it does not take table bookings — walk-in only (posted clearly on both the restaurant's Facebook and TikTok), and it accepts cash and bank transfer only, no credit cards. Anyone used to swiping a card should come prepared. Another rule: no outside food allowed in. The upside that makes up for it is a genuinely large parking lot, so driving there is easy. Weekends get busy enough that even MICHELIN itself notes you should arrive early on holidays. If you want a table without the gamble, get there before the 10:30 opening or avoid the lunch rush, and you'll get to eat your egg crab without watching the clock.
Kin Kub Koi
Per-person budget is flexible — starting around THB 250 for something light like fried prawn cakes, and running to THB 1,000+ if you go for the steamed egg crab with fresh milk (~THB 720) plus river prawns priced by weight. Important: the restaurant takes cash and bank transfer only, no credit cards, and does not accept table bookings under any circumstance — walk-in only. Call 094-666-9289 with any questions.
The restaurant sits on Phutthamonthon Sai 2 Road in the Thawi Watthana area, western Thonburi — no train line reaches it, so driving is the best option, since the parking lot is genuinely spacious. Open daily 10:30–20:30, with seating available until around 21:30. Weekday afternoons are fairly relaxed, but weekends draw big crowds — get there before the 10:30 opening or avoid the lunch rush. The restaurant has four seating zones and turns tables over quickly, so the wait is shorter than it looks. One more rule to know: no outside food allowed in.
