SunDog nailed it -- Legal Seafood. If I remember right (it's been about 10 years since I was to Boston) there are at least two. The one on the wharf is more expensive than the one in the mall up on the north side of town -- sorry, don't remember the mall name. Same menu, same food, but the prices are different. I went to the one in the mall several times while I was there -- mmmm, good stuff...
