Mam Tom Yum Kung

Tucked beside a parking building on Soi Kraisi in the Phra Nakhon district, this street food stall has earned a strong reputation for its tom yum kung — a hot and sour soup made with river prawns that visitors consistently describe as thick, creamy, and packed with umami depth. The stall gained wider attention after a recommendation from food travel personality Mark Wiens, drawing an international audience to what remains an authentically local, budget-friendly spot near the Khao San Road area. Beyond the signature soup, the menu includes salt and garlic prawns, fried rice, and omelettes generous enough to challenge two diners. The tom yum stands out for an unconventional detail noted by visitors: prawn heads are added directly to the broth, contributing extra richness to the flavour. Seafood is frequently praised for its freshness and size relative to the price, and portions are considered good value across the board. Good to know: the stall opens Tuesday through Sunday from 8am to 8pm and is closed on Mondays. Arriving during mid-morning helps avoid the busiest lunch periods. The setting is functional street-side seating rather than a comfortable sit-down environment, so those after a relaxed dining experience may want to keep that in mind. Taking a rideshare directly to the address is advisable, as the location can be difficult to find on foot for first-time visitors.
