We were just at Columbia House and the upstairs seating is very nice. Quiet and cool. The food was pretty good as counter service goes. They have a hummus sandwich, tuna sandwich (has lettuce and tomato on top, whole grain bread), fried fish, fried shrimp, and chicken nuggets.
The kid's menu was PB&J (uncrustable), mac & cheese, and chicken nuggets (I think). They can get grapes, applesauce, yogurt, or apple slices. They also have coleslaw and french fries.
Adult dessert was strawberry yogurt, apple crisp, or chocolate cake. You can also substitute a dessert for a bottled water if you're on the dining plan. Most folks in our group went for the apple crisp or bottled water. Chocolate cake was half frosting and too sweet. Would not recommend.
