Brown Derby Definitely! We loved the food there, service was great. More details in my review (link below) but I absolutely loved my oyster and brie cheese soup, and my black grouper entree.
If on the deluxe dining plan, worth 2 credits. If I was on the regular dining plan, I'd probably pay cash and save the credits for 2 other meals. However you pay.... appetizers are included with the fantasmic package.
Mama Melrose in 2009 was just OK. I had a tuna steak that was really dry and over spiced. Just grocery store variety frozen tuna. It's also a little further to walk to fantasmic than Brown Derby.
Hollywood and Vine - NO! Think very low quality budget college dorm buffet food. And lunch is no better. However, the breakfast with characters here was very nice.
