Was recommended to try here by a gentleman who has lived in the area for 54 years, and it did not disappoint! Drive down carefully – the roads are narrow – then free parking right at the water. Line was not bad. Prices were very reasonable and all food FRESH. Portions were great too.

Dissatisfied with the food. Ordered the CCC dinner meal. I choose clam strips, fried scallops, and coconut shrimp. Meal came with French fries & coleslaw. For $26 not worth it!! Waited an hour and 15 minutes for my food. Food was served to me cold & did not taste good. Was not going to wait to have another Oder made as i waited long enough. Other than that, the atmosphere was gorgeous & staff was friendly.

We go multiple times a year, and we are never disappointed ! It’s a beautiful place to grab some lobster and seafood, or burger and fries, even chicken tacos! Kids can look into the channel of water circling Costellos and find a variety of sealife. Admire the ships docked and sailing by. There’s cute lil birds and huge seagulls. This place is super laid back with picnic table seating or patio table and chairs. Bring a cooler with your own adult beverages if soda or water isn’t what you’d like to chase your lobster with.

I’ve had better Lobster rolls elsewhere…on a sesame seeds buns, was an odd choice. Needed more butter. I had never been there before, staff didn’t really instruct me on how their establishment works from ordering to pick up to drinks

They were busy and we got there RIGHT before closing so it took awhile- but it was worth it. Delicious, beautiful despite the weather, and being able to eat on the balcony and look down/out over the marina was great.

Dinner was great with good atmosphere, but they attempt to cram their ice cream (regardless of scoop number) into lids barely fit to hold one scoop. See photos for before and after reference. Costello’s: Please upgrade your cups!

Been here a couple of times before, and everything was good. Had an experience yesterday that motivated me to write my first google review. Went there for lunch on a beautiful day, and it was not very busy. Ordered food right away, and it took over 30 minutes to get to come out, including items from the raw bar. The fried food was cold, and the raw items were warm. We didn’t return it because we’ve had issues returning food before. For the prices they charge, they definitely need someone quality checking the food coming out, especially with the young seasonal staff I saw working the kitchen by themselves.

Recommended by AAA. First and last time we will be here. Waited about 30min for our order while the people before us got their $100.00 order and was almost done by the time we got ours. Oysters were warm and not on ice. Fish tacos were bland. Coleslaw was warm and no dressing. Table upstairs were all dirty and never cleaned by staff. Staff only came up to bring food. Will not be back.

Its self service. Order at window, food is dropped off at the table. If you order drinks, go back and pick up after they drop off the food.

Terrible food! The clam fritters were tiny and overdone. The tarter sauce was the consistency of water. The whole belly clams were more like strips for $26. Only a few were whole belly. The place is mostly run by teens and when we complained, there was no reaction, no refund, no apology…nothing! It was a waste of $48!
