Martingdale Wharf in Portsmouth, NH is a downtown landmark, and their gluten-free options are quite extensive. Nearly the entire menu can be made gluten free, with a few exceptions. They have a dedicated fryer for everything from calamari to clams, and fish and chips, along with burgers, vegetarian options, seafood jambalaya and more. And don’t forget the clam chowder! Waterfront, not a dedicated gluten-free facility, but super careful in the kitchen.
