It's surprising that Tom Yum Goong Banglamphu, the street vendor just a couple of blocks from the famed backpacker street Khao San Road, isn't overrun with foreigners eager to try their version of the hot, spicy and sour Thai classic, tom yum soup.
Perhaps it's the surroundings which could hardly be called upmarket - a typical shabby (albeit somewhat smartened in recent years) street food set up - a collection of tables and kitchen area huddled under an awning along Soi Kraisi. Or maybe it's the lure of Khao San Road's buzzy nightlight that stops guests venturing even a few roads over.
But those in the know and Bangkokians come here for one of the city's best tom yum soups, a perfectly balanced rendition that's slightly creamy from the shrimp fat. Expect juicy fresh water shrimps and a soup that's heavy on the kaffir lime leaves, galangal ginger and lemongrass, the three main ingredients that make up the classic Thai soup. Coconut shoots add a pleasing crunch and there's just the right kick from the chilli. Despite the humble surroundings, only the best possible ingredients are used here picked and cooked by the 'uncle' who runs the joint.
This isn't a place to come for the beautiful surroundings unless you like a typical street food setting (something I personally do). But the food is well worth braving the tyranny of Bangkok's midday sun.
There are several other plates on the menu and all are good. If you're sharing, explore the other salads and stir fries too. Prices here reflect the quality - a bowl at Tom Yum Goong Banglamphu starts at 150 THB (around US $5). The stall opens across the day from breakfast to dinner, but it's worth coming outside of peak hours.
