At Game Works in Grapevine they have a small area upstairs that has about a dozen or so classic games. THe ones I remember off hand are: Donkey Kong Jr., Frogger, Ms. Pac-Man, and Xevious. They are all mounted into oversized cabinets with benches to sit down at.
Not really many places in DFW to play classics anymore....there was a bowling alley in Garland that had about 20 classics up until 2 years ago, when they dumped them somewhere (and wouldn't tell me where).
Again, you should go to the auction in Mesquite on June 16. Best way to find games locally.
