This restaurant is perfect for a date or for bringing your parents out to a nice dinner. It has beautiful furniture, gorgeous lamps, artistic photographs on the walls, and a nice intimate atmosphere.
Having a large, almost completely vegan menu to choose from was great too. The food was good too. The desserts were fantastic. The vegan cheesecake is among the very best I ever ate. The service was great too.
If you are just hungry, and don't care about the atmosphere, I would recommend Bo De Duyen; the food is cheaper there and the atmosphere is more casual (and the food just a tiny bit better, I think). If you want a more elegant atmosphere, go to Happy Buddha.
