Heh, let me be a rare voice of dissent, in which I really do enjoy Brown Derby. I've had better meals there then some signatures out of the park, and they do decent drinks.
Their new dessert trio has been sadly a bit of a let down to me, though (I thought the big old desserts that were larger and you got a single of were much better) and I also think part of the appeal of this place is the delicious appetizers. So I wouldn't recommend for the basic dining plan, but if you have the deluxe or want a fantasmic package, I'd definitely go. Particularly for the later, as Mama Melrose and the Vine and Dine are just that horrible (well, okay, the first is just boringly medicate, but the last is horrible).
