Not sure what the seating arrangement will be like at JZ, but we got to Cotton Club around three hours early because we are losers were told we couldn't reserve seats ahead of time. So we chose a booth that looked nice and sat down. Moments later, we were told we couldn't sit there -- because that table was reserved. Huh? (There wasn't a "reserved" sign on the table.) We eventually sorted things out with the bar's super-cool, super-laid-back owner (sorry for raising our voice, Greg!) and we got our booth, but just warning you to be prepared for anything, as is generally the rule in China.
After that, however, service -- and, most importantly, the sound -- were all fantastic at Cotton Club. Try to get to JZ tonight if you can.
Got photos from last night? We'd love to see them. Email them to photos at shanghaiist.com or upload them to Flickr with the tag "shanghaiist."
