Behind the McDonald's on Silverbell Road, there's a bright blue building perched on the top of a hill. The lofty restaurant, Teresa's Mosaic Cafe, is shaped like a wheel, with large wooden beams strung with fluttering Mexican paper cuttings. At the center: a woman with a comal.   

The fresh tortillas that come off of it are the heart of this restaurant, elevating Sonoran standards like cheese crisps and huevos rancheros into quite extraordinary dishes. Puffy and warm with just a hint of chewiness, the corn tortillas felt natural on my fajitas tacos. Despite the fact that, well aren't they supposed to be on the side?

But over here, you can get fajitas made up into perfect bites, with curly strips of steak and soft onions and peppers and silken guacamole already on top. I guess when you've been around for 30 years, you can do whatever you want!   

Weird fact: On Teresa's website, you can watch the TV episode that made them famous, "Throwdown with Bobby Flay." They may have lost, but it was pretty funny watching Bobby Flay trip over the door at Hotel Congress ...
