I went there about a year ago, and my father used to go now and then. It was a Ravens' game night, so the parking lot was packed, but everybody was in the bar - the dining room was almost empty. Luckily you can't hear the bar from the restaurant.
I remember liking their crab imperial-stuffed mushroom, and my father raved about the shrimp dish he had, although I recall him saying that the quality of their food wasn't always consistent - maybe due to turnover in the kitchen.
But for crabs, I couldn't tell you. If you're just taking crabs home, there are a couple of other places on 152 which we've been to, and are pretty reliable.
