Life In 19x19

I have a free afternoon in Beijing tomorrow and would like to know if the China Weiqi Association is worth visiting? I've been to the Nihonkiin. They have a small but nice bookstore.

明天我在北京有些业余时间。我想问一下，去中国围棋协会有用吗？让人就进去？有书店还是什么的？谢谢。

I think they have a desk near the main entrance.
The person there may ask you what's your business there.
If you go with a pro, of course no problem.
Otherwise, I'm not sure...
