Costello's Famous Roast Beef And Seafood

This restaurant is in a great location, with attentive and friendly staff. The food and variety are outstanding. My favorite dish is the chicken parmesan sub—the way they chop the chicken creates a fantastic texture with every bite. You also won’t be disappointed with the steak and cheese sub; it's truly mouthwatering! I’m looking forward to their clam chowder coming soon. If you're looking for a place to sit down and enjoy a delicious meal in a relaxing atmosphere, this is the spot! Plus, they offer delivery—so spread the word: Costellos delivers!

This is the best restaurant in town! The owners are friendly, considerate, and very attentive to both the food and their customers. Everything about the place, from the ambiance to the cuisine, was absolutely outstanding! I would HIGHLY recommend dining here! You won't be disappointed.

I finally visited Costello's, and it definitely won't be my last time there! The food was delicious! I ordered the regular roast beef sandwich, and it was enormous! The onion rings were incredible as well! I'm excited to return because there are so many other dishes on the menu that I want to try. I can see why I had to circle the lot to find a parking spot! LOL

I visited Costello's for the first time and was thoroughly impressed. I ordered the seafood combo, and the fried clams were some of the best I've had in ages! They definitely didn't hold back on the scallops, shrimp, and haddock either. Everything we tried was delicious and fairly priced. The steak tips were cooked to perfection and incredibly tender, while the roast beef was simply superb. The dining area was quite pleasant, and the staff were courteous and attentive. Without a doubt, this is the best food around the 125 strip. We've found our new favorite restaurant in the Plaistow area!

Fantastic food, generous portions, and excellent prices! I've already been there twice this week, and I can't wait to return this weekend! So far, we've tried the steak tip Caesar salad, the chef salad (the house dressing is incredible), the steak and cheese sub, and the lobster roll. Everything has been delicious! The customer service is outstanding too!
