Mam Tom Yum Kung

Tucked beside a parking building on Soi Kraisi in the Phra Nakhon district, this street food stall has built a loyal following among locals and travellers alike for its tom yum kung — a hot and sour soup made with river prawns that reviewers consistently describe as thick, creamy, and packed with umami depth. The stall gained wider attention after being recommended by prominent food travel personality Mark Wiens, drawing an international crowd to what remains an authentically local, budget-friendly spot near the Khao San Road area. Beyond the signature soup, the menu extends to other seafood dishes including salt and garlic prawns and omelettes large enough to challenge two diners. The tom yum here stands out for an unconventional touch noted by visitors: prawn heads are added directly to the broth, contributing extra richness to the flavour. Portions are considered generous relative to the price point, and the seafood is frequently praised for its freshness and size. Good to know: the stall operates Tuesday through Sunday from 8am to 8pm, closing on Mondays. Arriving during mid-morning or early afternoon helps avoid peak lunch crowds. Given its street-side setting near a parking structure, seating is functional rather than comfortable, so those seeking a relaxed sit-down meal may want to plan accordingly. Taking a rideshare directly to the address is recommended, as the location can be tricky to find on foot for first-time visitors.
