It's been a while since I've been in Ocean City and I can't really comment on the price, but Phillip's is known for having some of the best steamed crabs and crab cakes in Maryland. If it's not too expensive, I'd recommend going there for dinner one night.
I had originally planned on trying it and figured it to be about 25 bucks. Which was just what I thought it would be worth. (We are on a vacation budget). However, Rob's mom told him she thought it was around 40 dollars, which is NOT going to fit into our budget. I had heard they were the best too, and was really looking forward to trying their seafood.
