That may have been the best service I've recieved at any restaurant I've eaten at in the almost two years I've lived in Arizona. Normally, it's annoying when a waitress asks me how I'm doing every 5 minutes, but she was not just trying to earn an extra buck. She was genuinely concerned.
The missing star is because of the style (or lack there is) in the music I heard there. The waitress said it was the bartender's iPod mix. Anyway, I'd bet that they normally play better music.
