This is the finest duck restaurant in all of China, reknowned for hosting world leaders. The fare was top-shelf, featuring the best duck money can buy. Interestingly, the ducks come certified, making known its quality, and are sequentially numbered from the first one served in 1864. Be careful if you choose to drink the Moutai; it is 150 proof and packs quite the surprise.
