I stayed at the Asia Hotel which is directly opposite this lovely restaurant - heaven !!!
The food gave me the opportunity to try the vegan versions of Cambodian and Khmer food. The food was very reasonably priced and delicious and in the evenings served with green tea. I was in Battambang for three nights and I ate every night at this restaurant. Although meats are on menu they are all mock meats made of soya and mushrooms.
This restaurant was opened from 8 am - 8 pm
Cons: staff only have very limited English, if vegan not good for breakfast
