This is one of those "create your own stir-fry" or "Mongolian barbecue" places where you pick your own veges, meats and sauces.
They have a pretty good selection of sauces. Try their roti prata (indian bread) that comes free with your stir-fry. Really good!
7 bucks for lunch, I think, is a damn good price for the amount of food that you can stack in your bowl. Dinner at $12 is probably a bit on the pricey side. I'd just go for lunch.
I was there for Sunday lunch and they were packed. I'd call ahead and make a reservation for weekend lunch.
