Chesterfield is a good option if you're looking to party on Wednesdays. Other than that it's best recommended to people who want to party with Moscow's students. A good choice on Wednesdays, otherwise decent if you're younger and want to drink a lot on a limited budget.
The Chesterfield Bar Moscow is a bar/club on the famous Novy Arbat street. It's a big venue that has a bit of a sports bar vibe even though there are no TV's inside. The crowd is younger and more "down to earth". Lots of students in Chesterfield, especially on Wednesdays when it's Ladies night.
There's offers for unlimited drinking: 1,000 Rubles for ladies every night, different prices for guys from 1,000 (Mondays) to 3,000 (Saturdays)
