Thonglor Express is a casual eatery near the British Museum and Tottenham Court Road serving Thai street food and comfort dishes. It offers khao soi, Sukhothai tom yum noodles, yen ta fo, green curry and mango sticky rice, ordered as a buffet or à la carte. At late lunch there is an unlimited buffet where diners choose several dishes, and food comes out quickly. The space is closer to a no-frills restaurant than a place with fancy facilities.
