I did the Pub Crawl in Shanghai one of my first weeks here and it is still hands down one of my favorite nightlife experiences! The staff is super friendly and really fun! I had such an awesome time with my friends we went the following weekend as well!
For 180RMB (if you RSVP) you get an open bar at the first bar and then drink deals at the next three as well as shots every time you get on the bus and at every location! This price is UNBEATABLE! Its so easy to meet other expats and have a great time! I highly recommend trying this out whether you are here a short time or staying awhile!
