Phenomenal sandwiches, I can't stress that enough. Possibly my favorite lunch spot in Phoenix. Also, it's a great place to stop by during first Friday's or whenever you're barhopping in downtown.
Their beer selection is fairly solid too considering its such a small place, and you tend to appreciate the quaint, authentic Arizona look when you're inside.
I'd recommend Carly's to anybody looking for an outstanding (and affordable) lunch.
