Once you leave Mexico, drinking tequila is a dodgy issue. Take a look at the bar at Mena's Palace, a beloved luncheonette in the French Quarter of New Orleans.  On the middle shelf you can find a couple of brands of tequila, "Juarez" and "Pepe Lopez," that I have never seen in Mexico. Call me skeptical, but I wouldn't disinfect my bathtub with that stuff. (I would also stay away from that bottle of  "Aristocrat" gin.) Something tells me that Mena's has Greek owners, because  on the bottom shelf they carry both Metaxa, a brandy I remember from my sojourn in Athens as a 20-year-old, and several brands of ouzo, including one that appears to be twelve years old.
