Great little place. One of my issues, of many, with Phoenix is there are no small places to grab lunch. Yeah for Zulu Caffe.
A little hard to find of you are using Mapquest si just shoot for the Scottsdale airport. The menu is small, but what there is is very good. and provides a variety of salads and sandwiches. Check out the brunch and lunch menu online.
The potato chip stack is utterly sublime and is addictive just as the server predicted. In fact, it's calling my name right now.
One word of warning, if you are on a diet take heed. Not much for dieting which is probably why it is so good.
