Check out Club Mass, a mix of world class DJs

A relatively new addition to the Seoul club scene (it opened October 2007), Club Mass makes world-class DJs and thousands of beautiful people crowded into the same room seem like an everyday occurrence.  A long, slick bar near the entrance serves the immense dance floor, which can sometimes make it difficult to get a cocktail, but the gorgeous bartenders and bouncers make it worth the trip.

With VIP lounges and a maze of stalls in the bathroom, Mass practically has it all- though at a fairly steep cover charge (20,000 Won for weekends, 15,000 for weeknights).  Special shows (generally on Saturday nights) can cost upwards of 40,000 Won, but it seems like pennies when you're dancing eye-level with famous DJs while they spin tracks on the raised dancefloor/stage or people-watching from the second-floor balconies.

The club is also incredibly accessible, set just off the main road between exits 6 and 7 of the Gangnam station- look for the massive crowds outside.
