Forgot the name but it is right next door to the hello kitty restaurant in Sanlitun. the place is decked out in Yunnan style decorations with a small log river running through it which is awesome. It is Yunnan hot pot i might add. But it is located on the top floor of the Shi Mao department store fairly new place that opened up this year on the corner of Gong ti bei road and Xindong road.

Dianke Dianlai is the best Yunnan restaurant I've been to in Beijing. You have to order a set meal however which includes over 10 courses with mouth-watering delectables. It's about 200 RMB per person but totally worth it. The ingredients are fresh and good quality and you'll experience a taste sensation that's new and absolutely mouth-wateringly good! Oh and it's set in a really cute courtyard building with an open roof seating area.
