Mainstream is a nice place to go for dinner with some friends or family. The food is good and the atmosphere is relaxed and quiet. The restaurant is probably suited best for adults as the focus is on the food and nice atmosphere, not having fun. The walls are lined with nice prints of fish and the ceiling is unique: it does not have panels, but instead is exposed so that you can see the air vents above. There is almost never a wait. Mainstream would be a good place to go with your parents, grandparents, or others of the like.
