Not much more that you can say about a convenience store. There biggest claim to fame is all about being a "health and fitness destination" because they carry a wide variety of protein bars and health drinks. Yes, but they also sell cigarettes, which kind of negates that claim a bit.
Still, a good convenience store if you're driving through Scottsdale.
