Yay! you're going to my hometown! :-) Well let's see, the Rokerij is a nice coffeeshop, veryyyy chill but also very touristy, so very overpriced... Check out some of the smaller, lesser known coffeeshops... Especially all around the red light district ;-) Clubs, unfortunately the Mazzo is closing soon, in the next few weeks I believe... You could check out Kingdom the Venue, on saturday nights they usually have some trance dj... Also Escape, thursdays they have funky house and a bit of tech house, at a night called Rush, and saturdays they have a night there called Chemistry. There are also other parties or dj's about in holland all the time... So depending on when you're going and what scene you prefer, I could maybe help you with that.. Tiesto's record shop is not in Amsterdam. It's 1,5 by train, and it's not really all that exciting, there all plenty of record stores in Amsterdam that are much better! Anyways, let me know if i need to help you with anything :-) oh, and I'd recommend either going to Germany, Spain or the UK
