Native Arizonan here: we love Mexican food!! Mexican food is my chicken soup, my default no fail friend. Since I started driving I was eating carne asada burritos around town as my go-to sustenance.
Vaqueros is all the good things I need in a fast Mexican place: dual drive through, large menu, horchata, red or green hot sauce, crispy tacos piled with shredded cheese!!
My favorite is the carne asada burrito- served super hot! Also the shredded beef tacos are awesome. I've gotten a combo with an enchilada before and both times the cheese inside was not melted. Also the chicken taco has a nice garlic flavor but not shredded chicken but diced.
The drive through girl is super nice! She recognizes her customers which is appreciated by regulars.
