I booked the FDP at Brown Derby and was told I could use 2 Free Dining Credits or pay 36.00 flat rate. Does this mean I can not order anything I want off the menu? It sounds like there is some sort of Prix Fixe menu. Can anyone tell me what the menu choices are? THanks. I'm thinking it would be way better to pay $36 than to use up 2 table service credits especially if you are picking from a limited menu.
