Beijing's Best Rooftop Dining?

This place gets a bit of stick, but I've had a couple of really memorable evenings here. The food is usually good (though towards the expensive end) but this is justified in the romantic setting - the dining room is handsomely decked out (some tables even have kitschy Vietnamese 'cyclo' seats) and the roof terrace can claim some of the best views in town, with the Drum and Bell Towers to the north, and Qianhai to the south, with Jingshan Park's pagoda clearly visible beyond. They're even touting it as a place to watch the October fireworks, so that's something I'll consider.
