Last night I was playing poker with some guys and we talked about the trip for a bit. They sometimes travel to Europe on business and explained that they don't do the tourist things, but they know the bars and places to hang out around cities like Amsterdam and London.

This is the type of thing we're looking for: The places that are often hidden to tourists. In asking for contributions, we want help in finding the bar-in-the-alley-with-no-sign type of places.

We would love to hear about the tourist stuff too, but in asking for first-hand info- we want to know what you discovered and can share.
