Previously tested in select markets in Washington, Colorado, and Southern California, the shakes come in flavors inspired by two of Panda's most popular dishes: "Orange Chicken" and "Broccoli Beef." The OC features a refreshing, vanilla-citrus base blended with pieces of real chicken and topped with a spicy-sweet orange drizzle, while the BB buries pieces of whole steamed broccoli beneath a sweet fusion of chocolate, beef, and soy sauce. Unlike their meal counterparts, each drink is part of Panda Express' "Wok Smart" menu at only 100 calories a pop, or 50 if you get them half and half.
