I'll chime in and give this location a ratings boost. The main thing they have going for them is their drive-thru. They always seem to move people through really quickly. The other location down on Chandler Ave always has a much longer line. They have a nice patio and lots of places to sit inside.
I have never had a poorly made mocha here and the staff has always been very friendly. I have never had an issue with service when going through the drive-thru and the few times I have gone in they were equally pleasant and efficient.
Not sure what all the hate is for. If you are on Ray this is a pretty great location.
