The Portman-Ritz Carlton complex is an expat haven on Nanjing Lu. This five-star hotel is optimal for business conferences, with dozens of meeting rooms, multiple bars, lounges, restaurants and a pretty eighth-floor terrace lawn which they open for special occasions. For a while, it was the tallest building in Jing'an, towering over the exhibition center across the street. Although it's tough to build an uglier complex (Shanghai has done it) the amenities contained in the center are nothing to sniff at: a World Link Medical, a pharmacy, bookstore, travel agency, supermarket and a handful of restaurants. No need to leave the complex!
