Sci-Fi for us. We got a bum waitress at our trip to 50s. She wasn't any fun. The children had heard all about the place and after a while they started throwing little hints at her hoping for some mama reaction. She still never responded, and they were bummed out. I wasn't as impressed at the food either. We all thoroughly LOVED the Sci-Fi. We LOVED the food there. It was on our do again list. 50s wasn't "bad", and the food wasn't bad, it just wasn't anything to write home about. It IS however one of the few places you can order Ratatouille, so if your children are fans of the movie that could be a plus, and since that's what I ordered, it was OK. Worth ordering, just nothing special. But then I rarely ever get a bad meal anywhere on Disney property.
