Taco Bell has just launched a new Cantina Bell menu, partnering with chef Lorena Garcia to create gourmet-inspired bowls and burritos featuring new ingredients for Taco Bell (including whole black beans; cilantro rice; all-white meat chicken in a citrus and herb marinade; guacamole made with Hass avocados; fire-roasted corn salsa; creamy cilantro dressing; and pico de gallo). As part of the launch, Draftfcb Orange County created print ads that broke this week in People and Us Weekly featuring QR codes made from fresh lemons and avocados. The codes link through to platefuls of information about the new menu and about Garcia (who was featured on NBC's America's Next Great Restaurant and will be on the new season of Bravo's Top Chef Masters later this summer). Critics will grouse that QR codes themselves are a bit of a lemon. But used in innovative ways, they can occasionally be appetitizing.
