I've had much better Greek food in Chicago, but Tempe is not Chicago!
The flaming saganaki is always fun for Greek food newbies, and the $6-7 lunch specials are tasty with both the gyros and chicken souvlaki. The Greek salad comes with a nice amount of feta on it, although they're a little skimpy with the olives. I don't go very often, but service at lunch has always been just fine.
