If you're using VKL, the best is to get the steak and lobster $39.99, the shrimp cocktail at $10.99, then the souvenir cup drink (it's usually rainbow icee but they'll give you soda), then get the dessert.
The lobster is stuffed with crab, it's half of a lobster. Not bad, the claw is pretty hefty - I wasn't impressed with the stuffing, with some butter sauce, it's not bad. The steak is either a NY strip or filet mignon. I had the NY strip and it was done just right. It's erved with some sauteed vegetables.
The bananas foster is quite good. It's a crepe filled with vanilla ice cream with caramel sauce drizzled on top and bananas scattered around, topped with whipped cream. Yummy.
DH had the apple cobbler and that was good too. He really liked the buffalo wings that he got for the appetizer, and I have to say I liked it too.
I think the servers at RFC are pretty used to seeing people come in with VKL. Our server (George) didn't even bat an eye... he even told us the best way to get our moneys worth out of the voucher.
Plus he told us that the child's voucher is treated the same as the adult voucher. That's the best deal. You order everything from the adult menu but with a child's voucher price.
