Cayton's was 100% my favorite place that I ate in Arizona. It's right up there with Hopdoddy in Austin if not equal. The location seems weird at first, but it's actually really nice and relaxing. It's right on their golf course, and if you go around sunset, you can get a great view with great food. It seems pretty upscale and really well done. Their burgers are amazing. Their homemade gluten free bread is some of the best I've ever had. I will be making a trip back to Tucson almost exclusively for these burgers. :)
I went back here, and I just wanted to report back that it is just as good as I remembered. I miss this place everyday that I'm not there. If you're in Tucson and you haven't been here, you are seriously missing out. They have great salads too, if you're not into burgers.
