Definitely one of the best Thai foods I've had in Thailand ever. If not THE best. It's prepared right there fresh on the spot, with fresh ingredients and no msg. Only two dishes contain eggs which On can leave out. She does use some sugar, so better to tell her to leave it out if you don't like that. Every main dish is 50 baht + 10 baht for brown rice. Drinking water is free (it's safe to drink as it's bottled water). I ate there 3 times in the 2.5 days I was there. On's place is all you need. Also meat eaters seam to love this place.
