September is... Belgian.

Every 6 weeks I have 4 days (3 nights) to spend away from Milan and, when I can travel, I do it!
So, now, I'm planning my new weekend! Hurrà for me!

From 20th to 23rd September I'll be in Belgium. Atm I'm so confused about where I'll sleep.
Bruxelles?
Bruges?
Gent?

I know there is someone who come from these 3 cities and is reading now, so let me hear your suggestions about where I can sleep, where I can find some music shops or/and where I can buy some quite unique clothing (t-shirts, especially) or/and where I can eat something special.

Thanks in advance.
