I went to Bruges with university friends in July 2009 (having also visited with family the year before).
After a pleasant walk around the cobbled streets and bridges (not forgetting the alcoves) we headed to a bar on the Grote Markt where we would end up spending a lot of time (and money) over the next three days.
We tried lots of Belgian beer - some of the better ones were: Bruge Zot, Duval, Kwak, Leffe (Blonde & Brun), Jupiler (of which we took a keg home), Chimay, Stella Artois (it is definitely better in Belgium) and Judas.
On our last day we climbed the Belfry, which involves a very narrow spiral staircase which is nauseating to climb - not to mention with a hangover.
