I've been there once so far and had just appetizers. A plate with 2 vegetable samosas for 10000 kip and a mixed vegetable Pakora for 12000 kip.
The place is a bit dirty and the staff not friendly, but the appetizers were incredible good. Pakora was not only fried vegetables, but with yummy spices on it. I double checked and it was both vegan.
Cons: dirty place, not friendly staff
