Casino Arizona.
No roulette in AZ... but big poker room and lots of slots.
Good food too...
Last time I was there, I grabbed a KILLER roast beef sandwich in their snack bar... stacked higher than the decks in the other room for about $5.

Just a hop skip and jump away from Tempe compared to the Gilas, Harrah' or Fort McDowell (which is getting rather dumpy)

John Long would probably be your best local guide
