Grumman78 has acquired something of a cult status in Montreal: when this truck pops up, Montrealers flock. I tried a taco for the second time at Juste Pour Nourrire, a street foodie off-shoot of the Just For Laughs festival. Everyone was there for the tacos, it seemed; it was the only stand that had a line up. This taco truck, it's got buzz. And a line it was: we waited for a long time;  the food was doled out very slowly as the people in line texted and tweeted on their phones in anticipation. \n\nWhile we were waiting in line, a girl leaned out of the taco truck to erase \"suckling pig\" from the chalkboard menu. They seem to make one unusual taco variety at a time, at least this particular festival. Some people gave up and forfeited their place in line in favor of easier-to-acquire food.\n\nBut I persevered, and was rewarded with a taco of the new flavour:  chorizo, black beans, and ranch salad. Very tasty, a great combination of flavours and textures, satisfying and filling. But I'm not sure it was worth 25 minutes in line.\n\nI would definitely try the tacos again, preferably in a non-festival, less crowded moment. They supposedly show up at Nouveau Palais (281 Bernard Ouest) every Wednesday, Thursday, Friday, and Saturday from midnight - 3AM. I'd suggest catching them there next time you're out late drinking in the Mile End.
