The problem there is, there are sit down Mexican places that don't cost any more and are infinitely better. Chipotle next to a shit sit down chain like El Torito's more expensive than all but a handful of Mexican spots. So yes, sorry I expect a GOOD burrito when it's as expensive as a sit down place. Your Morton's analog would work if BK was as expensive. BK sucks and it's CHEAP. Chipotle sucks and is EXPENSIVE for what you get. When I go to Taco Bell I don't expect much, and the cheap ass prices reflect that. $7 for a small burrito at Chipotle, sorry I expect a lot more for my money. And yes it's small for what you pay for it.
$1.50 cheaper then Chipotle, twice as much food and in another galaxy flavor wise. And it has nothing to do with authentic or not, of course it's not authentic. Food doesn't have to be authentic to be good, they can't even get that right though.
Never eaten there, but at worst it won't be good (the same) I don't see how it can be as bad or not as good. I need to go Yelp some reviews I think there's one somewhere around me.
*EDIT* Yelp'ed it, 1st picture showed a soda cup and it says "Mexican grill" on it, don't need to read a review this place is going to fucking suck donkey schlong. It could even be worse than Chipotle.
