I visited OTB (Over the Bar Bicycle Cafe) at the North Park Boathouse last fall with family while B was mountain biking in the area. The location is absolutely beautiful! The building is gorgeous and sets on a very picturesque lake. It's a perfect spot to dine outdoors during nice weather.
OTB offers burgers, sandwiches, salads, and bar food. Plus they have a pretty good beer list. I didn't get to try much from the menu, as we had dinner plans coming up, but I did try the Peel-Out Pierogies, which were really tasty, and the North Ridge Nachos, which were pretty good.
If you're checking out North Park, I think OTB is a great place to stop for a bite or a drink.
