There's always the Longstreet Casino about 10 miles north of Death Valley Junction, California. I think the only slot machines I saw there were penny slots. They have table games but they are usually closed, not enough business. The chicken fried steak and eggs breakfast in the cafe is $6.95 and huge. Free drinks if you are playing all 180 lines or whatever on the penny slots provided you can find someone to serve you.
OK, we went there as an alternative to eating in Death Valley, not exactly as a casino treat but it is low limit!
