My wife is an oyster nut and loves this place. We've been to many of the Manhattan seafood places and keep coming back here. There are normally at least four different oysters on the menu and the staff are very helpful in describing each. But my wife normally gets one of each on the first round then a dozen more of the ones she likes best. The waitstaff are well informed about the menu.
The only draw back is you either all need to like seafood, or somebody better be prepared to sacrifice. The none fish menu is sparse and is average at best. The sides are intended for seafood and just don't fit the meat selections. Its a terrible place for kids as the menu seems very rigid and not much selection for a 10 yo picky eater. Much better for couples. Desserts are varied. There is a fruit soup which is very good but the rest are uninspired. Eat here and grab a dessert someplace else.
The decor is fresh and modern. I would not call it romantic as most people seem to be having a business dinner. In the summer they will open a patio which is great for people watching.
