I am a frequent traveler to this eatery. I've yet to try a dish that wasn't outstanding. There Thai street food (mostly noodles) are all good but my favorite is the pad kee mow (Drunken Noodles). When i am not in the mood for noodles, their curries are excellent. My favorite is the Penang curry but their massaman is one of the best i have eaten anywhere, including Thailand.
My only negative is the service which can be a little erratic. The owner frequently is also the server and the kitchen can get behind. It is very annoying when one dish is served at a table with three or four diners and the others just sit and wait. By the time everyone gets served the first dish out is cooling off, maybe substantially. This is not unusual in lower end restaurants in Thailand but it is a bit disconcerting here.
PS They almost always have fresh mangoes and sticky rice for desert!
