The lobster roll was to die for. It was just a bunch of lobster on a hamburger roll...no fillers. The view there can't be beat. I will definitely go back!!

We absolutely love it here. We always come here each summer. It's become a tradition for us. The menu has a tad for everyone. The staffs are genuinely friendly. The food is delish. And the view could be to die for on a beautiful day.

Great, fast food. The only place that I like better is Bob 's Clams in Kittery, ME.

We went there today I ordered a fried clam dinner ( wanted lobster and steamers but the steamer was busted) my fried clams came out soggy and greasy......the fries were cold and greasy.......my girl had fried fish dinner..... It was pretty much the same......her clam chowder had sand and shell pieces in it......the clam cakes were good........here's the catch.....we ate at Costello's 2 years ago and it was a wonderful experience......perfection at its best...... I have no idea what happened......doubt if we'll be back.
