Injustice! We spent months waiting for Roxy’s Grilled Cheese Truck to hit the streets, and we rejoiced when it finally arrived in Cleveland Circle. So how sad are we that it’s not even there anymore? A couple of days ago, Roxy’s owners Tweeted that the truck had gone “missing” and claimed to be on a “manhunt.” Heh-heh. Yeah, not really. A tipster tells us that the truck is currently on the road, filming a hush-hush TV program and might return home this summer. Boston Restaurant Talk suggests following ‘em on their Foursquare page to learn more about their whereabouts. Yeah, we could do that. Or we could bemoan the loss of our grilled cheese!
