It’s on Parpetsi 16 street, Yerevan, Armenia (map).
I do not know yet if this bar can be considered as gay friendly to add it into my Armenia Gay Guide. But based on Onnik Krikorian’s comments and various photos I’ve seen, it seems like a free-spirited place, worth to visit and check out.
They have website (not properly functional, as of today) and Facebook group.
