My favorite part about Coffee Rush is sitting on the patio looking out at the "lake." Okay so I guess its a pathetic body of water, but for AZ it's something.
The coffee is really good, the baristas are friendly (most of the time), and I have always been able to find a spot to sit. They also have free wi-fi.
This is a great coffee shop to meet up with friends without feeling like you are the only people talking in the establishment.
Bonus: There is a Pita Jungle just around the corner.
Con: $5.00 card minimum.
