Definitely deserves the 5 star rating it has been receiving. I travelled solo to the Pub crawl and made friends within minutes of arrival. I did Friday night crawl the hosts were amazing made sure we were all looked after and helped with the translations. The crowd on Friday was mixed I would say 50% Foreigners but everyone really nice and happy to talk. Had such great night I actually went to the Saturday night crawl the following day.
I would definitely recommend for anyone who has not been Moscow before to go, as there would have been no way I would of found any of these bars myself.
