I'm usually a stickler when it comes to beverages of the alcoholish kind.

For example, I hate it when restaurants will refer to a Cosmopolitan as a "martini" just because it's served in a maritini glass. To me, it ain't a martini unless it's either gin or vodka with dry vermouth.....and olive brine is okay too if that happens to be your thing.
However......as odd as it might sound, some of the best
margaritas I've had have been at Chipotle.

(I know, I know. A counter service restaurant of all places.) Even the tasty Mexican restaurant/bar that used to be down the street from me couldn't touch them. (And they even had about 30 kinds of tequilla in their arsenal.) Maybe I like the ones at Chipotle because the one by me makes them really strong.

After just one I'm usually buzzy.
I'm not sure how the frozen margaritas at the Mexico kiosk compare since I haven't tried them, but they seem to have gotten several votes. I want to try one the next time I go.
