How can we have a good time with friends in Amsterdam?

Hey, guys! We're going to Amsterdam with friends for a couple of days and want to do more than just walk around the city; we want to have a really good time. Can you suggest some fun things to do together, places to have fun, or unusual ways to spend the evening?

My friends and I recently visited Amsterdam and were looking for something fun to do besides the usual sightseeing. We decided on Beer Bike - it's a large, friendly cycling group where you ride around the city, drink beer, and listen to music. It's really fun. You can check out the options and book right away at open now. I recommend it to everyone, especially if you want to have a great time with friends.

Can you explain how it works? How long are the rides and beer included, and are there any age or group restrictions?
