They carry a wide variety of dishes, but I've only tried a few, because the ones I've ordered have been of such high quality that I find myself re-ordering them. My personal favourites include the green curry chicken, which has a complexly spicy taste and a generous portion size, and the coconut milk and lemongrass soup with chicken. This pair makes a generous lunch at a startlingly slight price. I've been back many times but haven't found any dishes that I didn't like. This restaurant gives great food, but doesn't go all out for ambience.
Reservations are unnecessary, and the place is often almost full during lunch hour.
If you have an adventurous palate and have a taste for Thai, and aren't afraid to save a few bucks on lunch, check out Mae Phim.
