Luna is a street taco truck/trailer in the parking lot of a local title loan business. You can't miss the white trailer lined with flashing lights.
While you can eat on-site (there is one plastic table and chairs), the food is best taken to go. The menu board is to the left of the ordering window. While not abundant with menu items, there is a good selection of meat. Tacos or quesadillas are available in chorizo, chicken, barbacoa, al pastor or carne asada. There are several styles of Sonoran hot dogs as well.
The staff was very kind and friendly. The tacos and quesadillas were very good. They were not mind-blowing, but had good flavor, texture and freshness. I would eat here again.
