I like this place because it's unique. The restaurant is actually in a basement of the building hence the name Salt Cellar. I always go during Happy Hour when prices are cheaper because this place is rather expensive. Oh seating is not suitable for really large groups. There's a bar and then there are smaller tables in a separate small room.
Other than the prices, the food is good and the atmosphere is great. It has that private posh bar feel with dim lighting. Try the turtle soup, steamed mussels and the raw oysters. The steamed mussels can be eaten without any sauce. It's that tasty. The escargot is nice too. The baked oyster was kind of bland. But you'll have to try it yourself.
This place is for people that want to be fancy for the night. Eat and drink like an important person. Service is not bad and the food is good. And like I said, it's unique atmosphere. Just be prepared to pay the premium for it.
