The New England maritime theme of Columbia Harbour House features various sea faring items adorning the walls, and is complete with creaking wooden floorboards when moving from room to room. And there are quite a few rooms, upstairs and downstairs. The various seating areas are nicely separated, even though the restaurant itself is quite large.

Various seafood sandwiches are available along with fried shrimp and chicken baskets, grilled salmon, clam chowder, lobster rolls, and salads. A few select deserts are also available.
