Just thought I might post a warning, went to Brussels about a year ago it was quite good but I wouldn't recommend you go out in central Brussels at night as when I went there, there was a large amount of people selling "drugs" on the streets and just generally groups of rowdy youths. I guess its not really a surprise considering its a city just shocked me a bit as it seems so cultured and is so different during the day time.

Sorry to be reviving this but I wanted to leave a comment. I know that problems in Brussels are pretty bad but it's in every big city that you have these problems. Be careful, mind small alleys ;)
