Costello's Famous Roast Beef And Seafood

Awesome food, big portions, great prices. I've been there twice so far this week I can't wait to go back this weekend!! So far we have tried the steak tip caesar salad, chef salad, (house dressing is amazing). Steak and cheese sub and the lobster roll. All delicious!! Amazing customer service!!

Tried Costello's for the first time and was blown away. Tried the seafood combo and had the best fried clams in a long time! They don't skimp on the scallops, shrimp and Haddock either. Everything we ordered was delicious and reasonably priced. Steak tips were cooked perfectly and so tender. Their roast beef, perfection. The dining area was very nice and the employees were very courteous and attentive. Hands down, the best food on the 125 strip. Our new favorite restaurant when we are in the Plaistow area!

Best steak and cheese I’ve had in a very long time! Very friendly staff and the food comes out fast! I definitely recommend it to anyone in the area!

Very well located place, well respected employees, amazing food and choices, favorite food I get it is the chicken parm sub. They dice up the chicken which gives it that delicious finish when bitting into it. The steak and cheese sub is also something your jaw will drop for! Clam chowder coming soon and can't wait for! Please if you want to sit down somewhere and have a good meal with a relaxing atmosphere then come here! ALSO they deliver please share that with everyone COSTELLOS DELIVERS!!!

Best restaurant in town! The owners are kind, caring, and extremely attentive to the food and their customers. Everything about the restaurant, from the atmosphere to the food, was extremely superb! I would HIGHLY recommend this restaurant! You will not be disappointed.
