The Concertgebouw Ok, here's my Amsterdam Art Adventure 1. It's going to a concert in the Concertgebouw, my favorite place. The answer to these questions is, basically, no. Events in Amsterdam tend to be more relaxed and informal than what were used to in the State, so wear what you'd like.
Timing is important, though.
I suggest being there ahead of time, which gives you a chance to have a coffee in the lounge and peek inside the Concertgebouw's glorious birthday-cake interior. As for the Concertmaster, he's most likely practicing on stage when you get there. Its a splendid sight. Museum Plain 3. Night life 4.
