Windows too is one of the most successful bar in Shanghai, every one who stay in Shanghai about a month, and they will know this bar. As far as i know, it could be the cheapest bar in Shanghai too, so every single day, full of people, boys and girls like to go there a lot. And on the weekend i like to go there hanging out with my friends, get drunk is easy there because the drinks are cheap. If you are new to Shanghai, go to Windows too have a try.
