One of my favorites is the Chicken Breast Nuggets and Fish Basket, which comes with either steamed broccoli or french fries. Everything is crispy and perfectly cooked, and the servings are generous enough that we often split this. Menu items range between $9.00 and $11.00 and include Fried Fish or Shrimp Basket, Grilled Salmon for guests looking for something a little lighter, New England Clam Chowder and even a couple of salads. Kids entrees include the usual Macaroni & Cheese and Chicken Nuggets, but they also offer a Tuna Sandwich.
They have several menu items that were added in the last few year that I haven't had the chance to try, but I've heard they're pretty good. The Lobster Roll seems to be a point of contention, with some people loving it, and others really hating it, but most people just find it average. There are even two vegetarian options: the Lighthouse Sandwich & Chili. Columbia Harbour House is part of the Disney Dining Plan with Quick Service meals and some snack items.
The service is fairly quick and there is a lot of seating available. My favorite place to sit is on the second floor. If you sit in one of the gables near a window, you can see the Liberty Belle paddling along the Rivers of America out of the left windows. From the windows on the right, you can catch a glimpse of the Haunted Mansion. It's a great place to rest and relax and is rarely overcrowded. On a side note, the upstairs restrooms are very small and hard to find. They are tucked away in a corner near the left-hand staircase. I've heard the restroom location is actually in Fantasyland because Colonial buildings wouldn't have had indoor restrooms, but who knows. If you are traveling with an infant, I would recommend finding a different restroom, or at least trying the restroom on the first floor, which is much larger.
I love eating at the Columbia Harbour House and usually have lunch here every trip. If you're looking for good seafood on a budget, give Columbia Harbour House a try.
