BA and VA use the Delta Crown room in Orlando - no food just drinks but it does have a full bar service and is very spacious, it's situated airside very close the the gates.

You can use it if you are travelling in Business or Upper class or if you have a priority pass.

Not sure if you can buy access though.

Your other option if you get there early is to use Mcoys restaurant in the Hyatt Hotel inside the terminal, excellent and good value for money.
