Matts was recommended to us by some friends who are well familiar with the Phoenix area. apparently they have a few locations. This one is at Phoenix Sky Harbor airport (we were waiting for a flight). If you are at the airport and need a meal, you can't go wrong here.
We ordered the waffles, and a "Hog & Chick" (Two eggs, bacon, toast, potatoes). Fresh OJ to boot. I enjoyed the Hog&chick but the waffles are a better choice. Overall, not the greatest breakfast I have ever had, but for an airport, it's decent.
I have heard that the other locations are better. When I am back in town, I will try them.
