David Chang's Bang Bar is one of six fast-casual, counter-service options at the Block 16 Urban Food Hall inside the Cosmopolitan (which is also home to the chef's signature Momofuku restaurant if you prefer something a little fancier). However, Bang Bar has an engaging selection of quick bites in the $10-13 range that take advantage of spit-roasted meats sliced on the spot and prepared with an Asian influence.
Rob Kachelriess of Thrillist calls the U-Wrap "possibly the best $12 lunch on the Strip, especially if you choose the spicy pork over the teriyaki chicken." There's also a spicy eggplant version for vegetarians. It's basically a long burrito bent in the middle to form a "U" shape which, despite its clumsiness, packs a savory wallop of flavor.
The menu is rounded out with rice bowls, fold ups (think of 'em as bao bun tacos) and sides like pickled shishito peppers and chickpea dip with bread. The only misfire is an on-draft blood orange negroni that tastes more like a fruity vodka drink than an inspired take on the classic cocktail.
