Went to this place three times... and had more mixed feelings than the reviewer who calls this the 'best bar' in beijing.

I liked the mixed use of multi-level space, the interesting pizza menu, the multiple beer choices... but the roofdeck was the major draw, at least for me. Sadly all three times I was there, strong winds made the deck pretty miserable and one occasion forced them to close off this area completely. It seems this might be a characteristic of the location, so if you are planning on a rooftop experience in this area you might be better off heading to Sanlitun village or the Tongli Studio places if there is any sign of wind.

Where the place currently falls down is service - not in attitude as they are generally friendly, but consistent inability to take orders and deliver. They are trying and might get it right over time, but 2 of the 3 nights I visited, my small group ended up leaving angry and hungry. The third night DD's was cavernously empty and we didn't have as bad of an experience as I describe below, although it did take 15 minutes to get a service person's attention.

The first night, DD's was hosting two large parties with BBQ's. If you were not attending one of these events, service was very sparse. Although we were able to get drinks after much lobbying of confused waitresses, food was impossible. We ordered the same starters 3 times and after 1 hour of waiting we gave up and went somewhere else for dinner.

On the next occasion, tried their Monday night free pizza deal. I was expecting a crowd and waiting time for that, but when I arrived the place was only about 20% full. It took more than 20 minutes before a serving person to finally show up on the roof. Another 15 minutes for the drink to arrive. Another 20 minutes to the next serving person... all of the 20 people on the roof agitated and complaining, which I suspect led to serving people not wanting to climb the numerous stairs to deal with the customers. Anyway, when I tried to order food, was told it would be at least an hour before anything would be ready. Maybe this was because they had one pizza oven for a place capable of seating a few hundred people (vs the Tree which has 10% of the seating)? Hmmm. So we again left, I again had to call people headed to DD's to go somewhere else... in other words general mafan because they couldn't get the basics of serving food and drinks right.

On a positive note, the manager really seemed to care about the customers and spent a lot of time running around trying to serve drinks and deal with people's various complaints. So maybe they will iron out the kinks... but in the meantime, if you are hungry or planning a night with a group, I'd suggest you head elsewhere... at the very least call ahead to see if there are events taking place which will overwhelm the small kitchen and number of service staff.
