I went there at 8am and there was plenty of food. The staff (elder lady) didn't really pay any attention to me and didn't know how to order, if I should sit down or go to counter. But a friendly customer pointed at the counter and said something to the lady.. She was preparing a take-away meal which looked really good, so I said I wanted the same. It was brown rice with some kind of vegetable and three of four kind of tofu/mock meat dishes. It was really good and a good breakfast (I enjoy real meals as breakfast). It was very very good and really cheap, only cost me 30 baths. I really recommend it. Not spicy at all, there is chilly sauce for those who want spicy. Also easy to find, the spot is well marked here (through the Google map).
Cons: None, except a bit hard to get attention from staf
