I've been coming here somewhat regularly since they opened. It's a breath of fresh air in a strip mall full of nothing bust fast food and terrible chain restaurants. As others have said, the prices aren't the absolute cheapest, but you're only talking a dollar or something. I'm sure it would be about the same price as somewhere nearby like Rubio's.
The food is great; I particularly recommend the greek salad with gyro meat. It's enough food for two people!
