The center of Amsterdam is relatively small, but I found it a nice coincidence that the cafe was practically in front of the grachten house I had lived in for the month of December 1984. The Walem Cafe (seen below in a 1984 postcard but still in operation) is at address 449 Keizersgracht. I lived on the top floor of the eighth grachten house down to the left. Number 433.
Here is a photo taken by Joseph of the view across from our cafe on the Keizersgracht.
A swan swam up to our table begging for some appelgebak.
De IJsbreker was home to a small concert hall dedicated to contemporary music performance. It has an adjoining cafe where the public, performers, and composers could mingle before, after, and during concerts to consume large amounts of koffie verkeerd ("wrong" coffee) served in green cups with gold trim and strong Duvel Bier from Belgium.
It also was connected to an independent new music-friendly radio station the Concertzender. Willemien volunteered for them in the early '80s. http://homepage.mac.com/kaaawa/iblog/C394583283/E20071123180856/index.html
Today De IJsbreker cafe exists, and the coffee and appelgebak is as good as ever, but the vibrant new music scene has moved to the new and classy Muziekgebouw near the Central Station. http://amsterdam.arounder.com/muziekgebouw/
The "Brown Cafes" in Amsterdam are called so because of the nicotine-stained walls, but with the new smoking ban that just went in effect this summer, we found all public spaces to be smoke-free.This photo is of the Hoopman Irish Pub (a brown cafe) in the Leidseplein.
And yes, at the age of 16 Joseph can legally order his own beer or glass of wine.
Even for those who live in Amsterdam their entire lives, it is unlikely that they could visit all of the cafes in the city. But it would be fun to try.
