1) Leave the park - Beaches and Cream or one of the Boardwalk places are a short boat ride
2) 50's Prime Time - Good food, fun theme, slow, crowded waits as mentioned.
3) Sci-Fi - cute theme, roughly the same food as Beaches and Cream (burgers and shakes are what I recall anyway)
N/A) Mama's - haven't tried, not a fan of generic Italian to begin with.
N/A) Brown Derby - haven't tried for reason of the cost
