We decided to go there (twice in three days) based on reviews from TripAdvisor and we did not regret it. Place is groovy - i think is located in a garage, but looked nice and well organized. No aircon, but enough fans to keep you chilled (if chilled in Siem Reap is possible at all). I ate vegetarian both days (cambodian curry and fried vegetables) and my girlfriend had the grilled chicken breast with french fries.
Both portions were tasty, well presented and big in size (well u cant really get full from vegetables, but i already knew that).
I had also mango and berries shake - both tasty :D (a tick too thick for my taste, but i put some ice inside and it worked well).
Don't expect a star restaurant experience, but tasty local food with cheap prices. Some said cocktails were great, but we did not try them.
And also, they accept only cash.
