Our kids like CfA, and we probably get it at least once per month. It's by far our most common fast food purchase.
I suppose Taco Bell would make me grumpy, were I somehow forced to consume it at gunpoint. Nothing on the menu tastes like the original analog to its fast-food version. The taco meat does not taste like real taco meat, the beans do not taste like real refried beans, and even the cheese does not taste like real cheese, at least not to me. It's all pseudo-food, faux food. It's weird.
That said, I ate a boat-load of it in college, because there was one near the engineering buildings where I often spent late nights in the lab or studying in the library, and because it was super-cheap. $0.59 menu meant I could get two tacos and two burritos for $2.36.
