Chain: Taco Bell
Taco Bell is awesome on its own, with its 5-layer Burritos and Double Decker Tacos. But after all that food, sometimes you just need something to wash it all down. And perhaps the only thing better than a mojito or sangria to go with your Mexican food? The Baja Blast Freeze, of course. By now, the Baja Blast Freeze has become something of a household name for many foodies. It's an icy version of the Baja Blast, a lime-flavored Mountain Dew product, available only at Taco Bell. Apparently, the Baja Blast has been "chemically formulated to taste good with [Taco Bell's] food," according to Mountain Dew's wiki page. Can't argue with science!
