We're doing the same thing--spending a night at POP before moving to POFQ on our package. We're planning on the POP food court. That's actually the main reason we're staying there the first night (dd has been begging for another shot at the tie dyed cheesecake).
Our traditional first night dinner is always Boma. First night, then again towards the end of the trip (it's our fave).
But this year, we booked Cap'n Jacks at DTD for (what was supposed to be) our first night. (Then Southwest messed with their schedule, and we added the extra day at the beginning.)
Really, if you'll only be at POP for the one night, I'd probably do their food court. It has some rather famous dishes (chicken pasta alfredo comes to mind), they have some unique items (tie dyed cheesecake and bread), and they're one of the only (if not the only) resort food court to offer frozen coke drinks (like slushies).
