When i travel to Caltexico, I go by way of Moe's. Because although Chipotle and Qdoba do a fine fast food burrito, they don't do it as well as Moe's.
And it is fast food, but it pains me to categorize it in that fashion, because when I say fast food, you're thinking Taco Bell. . . and it's not THAT. It's a step up. The comparison is perhaps equivalent to a Red Robin to Wendy's sort of thing. Red Robin is to Wendy's what Moe's is to Taco Bell.
It's fast (though if you go at noon for a lunch hour meal, you'll question ANY categorization of their food involving the adjective "fast"), but good.
I go with the Joey Bag o' Donuts burrito combo with steak and black beans. Yum. I'm full now.
