Moscow has a lot of wealthy people looking for somewhere to spend their hard earned roubles, and a correspondingly high number of places for them to do it. The nightlife in Moscow is a real highlight of the city, and there is a huge variety of places to go to, and something for every taste.
Many of the best bars to go to are located in the large hotels, and you can expect them to still be there the next night, however some of the independent places will close and reopen without warning.
The night tends to revolve around Vodka, and with thousands of different varieties to choose from in the city, there will be something for everyone to enjoy.
Clubs can be open up until 6am, and the party rarely starts until midnight in the larger clubs like Khaos, giving you plenty of time to have a reasonable meal before heading to a club.
Western men in Moscow do tend to attract plenty of attention from local girls, and this can cause friction in certain bars, although on the whole Moscow is a place where you can enjoy yourself without looking over your shoulder all the time.
