This mini-chain has various locations around the city. I ate at the one on E 13th st. near Union Square, so I can only vouch for the food at this one. Probably the furthest from Khao soi I've had yet. More like a yellow coconut curry broth with some noodles, no sourness (why do many thai restaurants seem scared to make it truly sour?) and no toppings to speak off. Tasty nonetheless, but not Khao soi by any stretch of the imagination. The dish is called Chiang Mai noodles here. 'Nuff said.
