The standouts for us were the milkshake and the Celebration cheesecake someone mentioned. The onion rings were absolutely perfect onion rings, but nothing more.
Everything else was perfectly fine,... as in I have absolutely no complaints; it tasted good, used quality ingredients, and was prepared properly, but it also didn't blow me away. I had the shrimp pasta, DH had the tofu, and he also had the apple crumble for dessert. It's been compared to Applebee's and it is that *type* of food, but I think the quality is significantly better at Sci-Fi (or else the Applebee's by my house is just a bad example).
But go for the experience, not for the food.
