Well, i think you will get a slew of answers here. lol We walked into Harbour House our last trip, we were hot and all we smelled was grease. they have fantastic looking food, but DH wanted to try somewhere else. So we headed up to Pinochio Haus. The food was OK...DH said his sandwich was good. I LOVED the decor. Stay on the main floor, walk towards the front of the restaurant. We had the entire section to ourselves and i really enjoyed the murals and coo coo clock...really like a little german house. So cute!
Food wise, Cosmic Rays hands down. You can eat in, eat out, all types of food are there. I LOVE their Greek Salad. The salad bar is great too. I always grab some tomatoes for the kids there...any vegetable helps between ice cream and popcorn!

We have always been fans of Pecos Bills, but I think in the last 3 trips, we've exhausted the place.
Lastly, a small tucked away area we REALLY enjoyed was Sleepy Hollow. Not a huge menu, more light lunch type of place. We went for a snack after BBB and PL (before lunch) and DS ordered as his snack cream of (something) soup. Good enough... that's what he ate. I hate funnel cake.

These are our favs... depends on our mood. But we are very excited to get back to Cosmic Rays... if you can find seats facing the castle, it's usually less busy in that area. (and you can eat on the patio facing the castle too!)
