Here's my quick run down...
Mama Melrose - OK, but nothing special. We have restaurants like this at home. No big thrill.
Hollywood & Vine - like the character breakfast especially now that Agent Oso and Handy Manny are there. Breakfast food was good. Lunch and Dinner, food not so good.
50s Prime Time - I liked the theme and the food at lunch. Not too much kidding around but a little bit of fun. Love the milkshakes. Will definitely return again!
SciFi Diner - Fun for DS to sit in the cars and watch the movie clips but it's the same clips in 2010 that we saw in 2009. Food is so, so.... but the burgers, reuben sandwich, fries and onion rings were fine. The rest, I could skip. Probably not coming back.
Brown Derby - Really enjoyed the food and will definitely return since we like the fantasmic package. We don't care for the alternatives (MM, H&V) for the fantasmic package. Had some nice appetizers, black grouper entree, and I liked the filet too! (We ate here twice.....)
