When I arrived in Bangkok, Nguan Lee was the restaurant my family brought me to at 1am. It’s a great place for late night food, they’re open until 4am, and there’s a man that sells roasted chestnuts just outside their restaurant. I’ve been here several times for late night food, and generally the service has been good and the food orders come out promptly. I wouldn’t call the food here the best Thai-Chinese food in Bangkok, but it’s pretty delicious to eat at 3am! Not too far from here is Wine Bridge and Falla Bella, two very popular bars.
