I found this food stand near Tucson airport and had a very enjoyable meal. Quite frankly, I think the food at the airport is uninspired, so I drove around to try to find something to eat before I caught my flight. On a Sunday, many of the weekday options around the airport are closed. Luckily, this stand was open, clearly staffed by a hard-working family.
As you can see from the menu, they serve a variety of fruit drinks and fruit salads as well as savory dishes.
My order started off with a taquito made of beef head (cabeza). The meat was very tasty but not overly strong, just enough to make me wish I had ordered more of it. The burro's chicken was very juicy. The avocado complemented the meat very well in flavor, texture, and coolness. Even the simple lettuce made a nice contrast. I asked for my mango drink with a combination of crushed ice and water. I don't always order fruit drinks with my Mexican meals but perhaps I should change my habits---the sweetness of the mango contrasted with the savory meat just enough to highlight both.
