A botanical garden/gig venue? How strange. Brussels looks very nice; I shall have to there one day.
It's a fab venue! Plus, there are three concert halls, and two of them are really amazing. One of them looks like a tiny amphitheatre, the other is more kind of a wine cellar. :)If you ever come over to Brussels, I'll guide you around. ;)
That sounds great. Oh, and I can't believe I missed the word 'go' out of my first comment; I hate myself right now.
