Lines have been known to stretch way down the street at busy times for this jaunty, no-frills emporium, where the food is excellent and fresh as can be. The menu is pretty simple—just choose from burritos, tacos, fajitas or salad, then your main meat or veg ingredients, and one of several kinds of salsa. (Brave souls will want to try the fiery naga; the less masochistic may prefer the tasty salsa verde.) Wash it all down with a soda or a nice cold bottle of Mexican beer. Boojum has a few tables, but most people get theirs to go. Other branches are on Chichester Street (028/9023-0600) and Great Victoria Street (028/9023-3200)—or, if you’re lucky, you might spot the Boojum food truck somewhere around town.
