I have a 5 hour layover tomorrow in Memphis (don't ask). I know the airport has wifi now, but I would like to spend this 5 hours somewhere comfortable and fun (i.e. not the airport) and where the wifi is free (again, not the airport).

I will have a rental car, so I can go pretty much anywhere. Anyone got a favorite spot?

I did cross post this in the South travel & dining forum, but then realized it's more likely to get a response here. Mea culpa.
