I love this place - you can trust that everything they sell is fresh. They have a pretty big variety of offerings, from the typical (salmon) to more unusual (shark). Their prices range from the high to the very low. Buying the entire fish is much cheaper - and they'll clean it out and de-bone it for you for free, so that's a great way to get a bargain. Their littleneck clams are wonderful grilled. Oysters are just 79 cents each and they usually have three different types. There's a small grocery here too where you can get everything you need for a gourmet meal, including fresh flowers!
Pros: High end seafood for decent prices. Nice selection - try something new!
Cons: Wish they were open Sundays. Some employees more knowledgeable than others
