Yes, someone said about the footy earlier and I was thinking errr Leidersplein? Serious? No footy? Watched two play offs for Brighton v Derby and Sheff Wed in Leidersplein and the fantastic Cafe Eijlders is there, just off the beaten track too.
-> Cafe Eijlders <- became my most recent favourite bar in Amsterdam, spent a fair few hours in there drinking fantastic Belgium beer. One word of warning though, however drunk you get, don't go dancing on the edges of canals, I had to be dragged out of one!
