The food is very good here and it's a place I like to visit on a regular basis (Joo Chiat branch).
If you're looking to get food from the outside buffet over lunch, make sure you're not too late (esp. on the Buddhist holidays), otherwise most things will be sold out. Brown rice available. Rice + 3 veg ~= 4 - 5 S$
The a la carte menu offers a wide variety of dishes, even if you are not in the mock meats. They also offer take out.
