They do have a GF menu, it is just included as part of the regular menu. They offer pasta, and a GF bun for burgers and sandwiches. I had an omelette and thought I was only limited to a side of sliced tomatoes, but the server was very helpful and said I could have fruit or a salad was well. They fruit side was very good as was the omelette.
They do offer other desserts that are GF. Even though they aren't traditional cheesecake they are still tasty.
