When I was in Beijing, I went to the 798 Art Space. I’d been there a few years ago and this time it seemed more commercialized. While there were cafes and shops before there seem to be more or else there just seemed to be fewer galleries open. Some galleries have started to charge and although they just asked for 10 rmb, that adds up and in a country with so many fantastic museums that are free paying made no sense.
I was pleased that I figured out how to get out to 798 on public transportation. You can just take the subway to Dongzhimen and then a bus out to 798. Beijing cabbies overcharge tourists relentlessly.
