the nightlife in Amsterdam, the most popular club ATM is Jimmy Woo, but you have to look out of club Panama as well. On Rembrandtplein (the square where you start your evening) you got some more commerciel clubs like the Escape and Sinners in Heaven (don't know if it's still open, it's been a while). For bars it's all located around Rembrandtplein. The gay district is great too (have maansteeg, regulierdwarsstraat) but I don't kow if that is what ur looking for, but it's all nice. Amsterdam is great, you'll find out for yourself. Trust me. Good luck on your trip.
