We found this really odd ad in the latest issue of the SH magazine, and apparently it has been there for some time already. Well it looks like Windows Tembo at 66 Shanxi Bei Lu has been offering RMB30 open bars every Thursday. Can someone enlighten us please — how on earth can bars offer RMB30 drink-all-you-can and actually make a profit? Has any Shanghaiist been there before? If anyone has been there and NOT had a hangover the next day, tell us please cos that is where you will find the entire Shanghaiist team this Thursday!
