I was there during the opening yesterday. The place was packed (I think mainly due to a promotion) and they probably still need to work out some operational kinks.
I must say, though a bit pricey, I had the best cup of coffee I've had here in Beijing by far at their 'discovery bar'. It was a pour over, filtered coffee made by the owner of the place. I forget his name, but I won't forget that coffee. I'll def be back.
