This place looked very cheap when I walked in and the only reason I decided to stay for a meal was because of the very friendly owner/manager. He cooked up a vegan plate of rice with vegetables and I was surprised of how good it tasted and it only cost me 40 Baht (the menu said 35 but no big deal). It's possible they use MSG but I'm not sure. I would have come back many times had it not been so far from my hotel.
Cons: very basic, possible msg
