Crash landing in the Da Tong Bar Mill is D10 Ultra Lounge -- "the longest themed ultra lounge in the world". D10 is built to resemble a commercial airliner, and they take the theme to extremes with air stewardesses as waitresses, captains as bartenders, airplane toilets, and DJs as pilots. The club is split into three sections: Economy Class (dance floor and stool seating), Business Class (lounge seating), and First Class (a VIP room). Drinks are 50rmb and up, hip hop is the order of the day, and you're clear for take off.
