I've been going here since I was a kid. Their prices are very fair - especially considering they have delicious New England classics. Their seafood is very good, so is their chowder, but their piece de resistance is the Buffalo chicken sandwich. Simple and superb. The interior is a little dated, like going into a diner, but that's not what you're here for. It's the food and quality staff/service. You get that smaller town feel from the staff as they're very friendly and amicable. If you're nearby, definitely drop in for lunch.
