The NF club is a reasonable choice,but you'll have to stay till 02:00 to get reasonable price and that isn't sure even,since you are not a Russian speaker. I'm usually using the newspaper(Moscow Times),don't be shy to give her 100 rubles for taxi if you don't like her and call for another!Start from 2 hours,it is no problem to prolonge(you'll save up to 50$ that way!). Have a nice stay!
