First time here this season and was totally looking forward to that hot lobster roll. Saw on the menu this time a OMG lobster roll for 24.95 vs the classic for 18.95. Total disappointment�. Almost all claw meat. Last years classic was scrumptious with lots of real lobster meat.

I have been waiting for a long time to try this place and I was very disappointed, stuffed clams were not properly heated threw, clam fritters were like biting a tennis 🎾, and I had the ccc plater the food was hot and the seafood fresh but lacked flavor
