Formerly a German colony during Tianjin's "concession years" this district now boasts some of the area's best lodging options, such as the Sheraton Tianjin Hotel, the city's only five star lodging, the impossibly huge Tianjin Grand Hotel, and the impressive Geneva Hotel. Out of all its dining options, however, the Quanjude Roast Duck Factory ranks as its most popular. It is one of the only restaurants in Tianjin that serves authentic Beijing duck. Several universities and parks including the Yinhe Park and Tianjin Amusement Park are located in Hexi.
