Well rev, I can't suggest any amps all that close to the airport.
Just go down and catch a cab and ask them to take you to Dallas. Probably the closest amps are Cleopatra and Aloha on Northwest Highway just a couple of blocks west of I-35E. Ask the driver to either wait for you or come back in an hour.
He could also take you to Jade (same as Hawaii Spa) or 7th Heaven. Addresses are in the sticky at the top of this forum.
You have plenty of time. They will be open until 3 AM or so.
Hope this helps.
