where to buy in Europe?

Hey. In about a month I'm going to Europe. This is my first "big" travel. My plan is to experience everything i can't in my country, Argentina.
Since there are no rpg shops here, all my old books are used and the new ones were brought through amazon or similar. in the 90's and 00's we had some corners in some comic stores dedicated to d&d and other rpgs. But I miss that time.
So, I have never been in a real rpg/game store.
I want to know how it is. I don't think I'm going to do a big purchase, just know how it is.

I'm going to be in: París, London, Ámsterdam, bruges, Berlín and Munich.
I would like to know if you can recommend me some game store in one of that places.

The Orcs Nest in London is quite good (it's the only one I've been to though, so there may be some better ones)

Orcs Nest is a good call, as it has the advantage of being in the centre of London.

I would also suggest that Leisure Games is even better - although it is about 45 minutes out from the centre.

Thanks guys. Do you think I could get the new dragon age book in the orc nest?
