i would say quality of food wise qdoba and chipotle are pretty much identical, though when i'm in a situation where i have a choice to opt for one over the other i.e. in new brunswick where a narrow side street is literally all that separates the two from each other i always opt for qdoba cuz not only does it have less people in at any given time (want to give my business to the underdog), but the often more crowded chipotle is full of frat/bro types and or hipsters that have become caricatures of themselves with ironic mustaches and those stupid tiny brimmed caps bike enthusiasts are about for whatever reason.
as for my lunch today i got some awesome ribs and rice from the portuguese bbq place by me which was, as usual, far too large a portion to finish in one sitting, so i've got awesome leftovers for lunch at work tomorrow too.
