We were visiting Groton Long Point for our annual family get-together. Costello's clams are the best (my wife loves the lobster rolls and/or boiled lobsters). The dining is outdoor over looking the marina, Lots of boat traffic. Always packed.

My son loved his lobster tail and I loved my shrimp taco. I forgot to order the gluten free tortilla and they were kind to replace it for me w/o a problem. Very friendly & helpful staff. Casual and shaded. Great views of the marina.
