Hi Adam,
I am familiar with De Bierkoning but didn't go this time. Sad to say, Café Gollem remains firmly shut; you can peer in the window and it looks like it is unchanged inside but it must be over a year now since it was last open. I was told (a few months back) that the problem was a legal one (licencing or something). They do have two other outlets, but these are not all that central.
