We ate there just about two weeks ago. Had excellent service, kids loved the waiter that walked around and did magic for the children. Our waitresss made very good suggestions for wines by the glass as I drank white (I had the Fulton's house white) and DH had a red.
DH & DD5 had lobster tails, DH had surf & turf, said his lobster and filet were both very good. DD5 gobbled that tail up in seconds flat. I had king crab claws, fantastic. DD3 ate off the kids menu, mac and cheese.
Overall very good. DH grew up outside Boston and worked in his uncle's seafood restaurant. He's super picky about seafood and has a great palate, and he was pleased with the quality of the seafood at Fulton's. We'd go back in a heartbeat.
