Porthole

Porthole is a classic Northeast diner on Custom House Wharf in Portland's working waterfront, known for seafood from Casco Bay and its Twin Lobster Dinner. The menu runs from all-day breakfast, including corned beef hash, benedicts and a lobster omelette, through lunch and dinner with fried seafood, lobster rolls, sandwiches and steaks, to a kids menu, desserts and a drinks list with local draft beer.

It is open daily, with the kitchen running from 7 AM to 9 PM and the bar staying open later on Friday and Saturday nights. The restaurant hosts live music and private events, and it also runs Casablanca Cruises from the wharf. Parties of eight or more are charged a 20% gratuity.
