Official "Dassai Bars" exist in several major cities, including New York, dedicated to the famous sake brand. This is Shanghai's first. More of a sit-down dining affair than a bar, it's located on the ground floor of the M-Town complex out by Hongqiao Lu. Although they do serve some food, the focus of the menu are the two pages of Dassai sake. Prices start at 98rmb for a glass of 50%, and goes all the way up to premium stuff like the Migaki Sonosakihe "Beyond" (6,800rmb), which they don't sell by the glass. They've got a 380rmb taster set, which includes a 50, a 39 and a 23, with a tiny primer leaflet and colored strings tied around the glass stems so you can tell which clear liquid is which. Considering you can get bottles of the same for half-price on Taobao, it's hard to recommend for anyone who isn't a big fan of the brand or wants to support their fully above-board purchasing channels.
