Was in Guangzhou on June 26. Went there by following the address listed here but had no luck. Heard from a bar tender from a pub nearby who mentioned that he had been approached by a lot of guys asking the very same question regarding the exact location of this bear bar. Unfortunately, it seems that Travel Gay Asia did not verify the accuracy of information published on their website, a shortfall of User Generated Content (UGCs)???

We went there on a Saturday night and there was nothing happening. The whole Creative Park seems to be shut down at night, so I assume either the bar has closed or it moved. Went to a brewery on this address that had bad beer and quite expensive for Chinese standards. Don't waste your time.

海珠区朗晴居旁(江湾路西) So y'all don't waste your time.

Also struggled at first to find A12 but eventually found the correct location and concluded this bar was either closed down or not open on Sunday nights.

Walked around Creative Park for 40 mins. Signs to A 12 sometimes pointed north, sometimes south, sometimes were just listed. People I asked were obliging but couldn't really help me. One of them said that if I didn't find it, I should join his birthday party in one of the bars there. I spent the evening with him and a group of 25 year old bankers singing karaoke getting pissed. I doubt that I'd've had such a good time at Bear Pub. But I'll never know until someone puts some useful signage in.
