I've cut way back on fast food during the past several years, and have yet to try BK in Beijing outside of the airport, but I have a number of friends who salivate at the very mention of going to the Xinguangtiandi location. Once I suggested that since it would take us 20 minutes to get there, McD's (literally 50 meters away) might make more sense, and they glared at me as if I was insane.
