Two of us tried this (May 2013) on the strength of largely favourable reviews on Tripadvisor and a positive notice in Time Out by Melissa Leong. They were right. Elegant decor there's none; it's a functional coffee-shop sort of space. You can see right into the kitchen (which looks clean and efficient!). You get a large menu to choose from, including a number of things that most westerners probably aren't going to try, and a lot of more familiar standards. Since the staff were speaking their language to many of the customers, I'd guess that most customers were Thai, which was a good sign. Meals are served pronto. Helpings are large. Food is tasty. Prices are quite reasonable -- four dinner dishes plus rice were $46 (tax and service included).
