House of Blues is very good and right across from Disney Quest. We've tried many different things and always been very happy. It's a fun atmosphere with lots of art to look at and good music playing. Here is a link to their menu. HOB Menu
We ate at the Rainforest Cafe on our last trip. Great atmosphere for children! The food is excellent. We ate calamari as an appetizer, then I had the chicken fried chicken with country gravy. Forgot what my fiance' had, it's been a year so my memory is a little rough!
I like Rainforest for the food and atmosphere, but the service has always been kind of spotty. I ate at Portobello last time and the food and service were great, but it is a little more expensive. If you do DQ then you can eat at the Cheesecake Factory there.
