My impression of this place could not have been worse! It used to be a nice and friendly place under the previous owner, but the new owner doesn't seem to care much for hygiene at all. The place was incredibly dirty and smelly when I went there. On top of it all, the owner will talk to you in Dutch, of course, but when I tried to explain I didn't speak Dutch well, he shouted at me. That was one of the worse experiences as a foreigner in the Netherlands.
The place is now close for renovations. I hope they will renovate their mentality as well!
Banning smoking in this place might just make it much more apealing for the (many) non-smokers or otherwise do please install a separate smoking room for the smokers!
