Check out the "pig" at the Lido hotel or ("Lee Doo fun dee ann" as the taxistas know it). It's a bit out of the way from where most of us will be staying. A smaller bar, gals a bit more aggressive and negotiable on pricing. Also a good number of Mongolian gals here.

Ok, going through my notes here's the address:

Pig and Thistle (Holiday Inn Lido)
Pig and Thistle in the Holiday Inn Lido Hotel
Jiang Tai Rd., Chaoyang District

There is a BBS area near here, but can't recall the exact directions. Walk around the block and some mamasan or tout hag will accost you for sure.

Two thumbs up for this place. A mix of Mongolian and Chinese girls, while Maggies has mostly Mongolian wgs (the Chinese ones there rarely go out with customers and work for the bar).
