Social House is a restaurant and bar with a nice view on Plaza Indonesia's roundabout. The atmosphere is supposed to be the feel-like-home type, but it is actually one of the hippest venues in Jakarta, so you don't feel that comfortable. Many celebrities and models come here, literally dozens of them on any weekend night.
I tasted the pizza there and it was not worth what I paid for it: It was very small and not well-cooked. Drinks are very expensive as well.
Social House is sometimes just called SoHo and it's part of the group Ismaya, behind Blowfish and Dragonfly.
For information about the events in Social House, I recommend you to check its facebook fanpage SoHo Jakarta.
