Unless we were specifically looking for it, we probably would have driven right by El Gran Burrito. Located about 1/2 a mile down the street from Monte Alban, El Gran Burrito is a small trailer in a parking lot of an auto garage. There is just one guy working on board (on the menu the name Juan Gonzalez was written) and the kitchen inside the truck was pretty simple. The menu is very small; tacos are $7 for 5, a burrito is $6 and quesadillas were $5. We definitely brought our appetites and everyone ordered all three options and tried every meat that was available that night.
