ObAroi Kaset-Nawamin
288 Prasert-Manukit Rd, Chorakhe Bua, Lat Phrao, Bangkok 10230
Order the grilled river prawns first. The kitchen's identity sits on prawns and the ob-aroi house seafood sauce, and the ฿900 plate is the order that justifies the trip out to Kaset-Nawamin. Add the baked prawns with vermicelli to round the table. Skip the long deliberation over the dessert list and let the seafood carry.
Pull up off Praseritmanukit Road in Lat Phrao, walk in, and the menu sits squarely in Thai seafood territory: river prawns, oysters, crab, sea bass, and squid, with a long signature list run by the Ob-Aroi By Kob group.
The headliner is the grilled river prawn. ฿450 for one, ฿900 for a plate, and the kitchen finishes them with the ob-aroi house seafood sauce that the brand built itself around. Fresh giant oysters with chili sauce land at ฿360, baked prawns with vermicelli at ฿330, and marinated raw shrimp in special fish sauce at ฿240.
Grilled sea bass arrives at ฿420, and crab in special fish sauce moves between ฿600 and ฿800 depending on size. The full menu runs over 30 items, with fried fish cakes, crab fried rice, squid plates, fish curries, soups, and a dessert section that closes with mango sticky rice.
The Ob-Aroi group operates two branches. This one is the Kaset-Nawamin location at 288 Praseritmonukij Road, Lad Prao 10230, with the original on Prannok-Tat Mai in Bangkok Noi. The brand's tagline says they cook with heart and serve with heart, which is the language they push on every channel and which matches the family-run feel of the dining room.
Getting here is a Grab or taxi job. There is no MRT or BTS in walking range, so plan the ride. Reserve by phone on 063-494-9556 or 097-449-6569 before weekend dinner. Come with at least three people if you want to share a full river prawn plate without compromising the rest of the table.
