In continental Europe, the word café often means a bar where alcohol is available. At one time there were many cafe-coffeeshops in the Netherlands where beer and cannabis were available.
The 1995 regulations sought to separate alcohol and cannabis but existing cafe-coffeeshops were allowed to carry on selling both until 1st April 2007 when the remaining cafe-coffeeshops in Amsterdam were forced to choose between weed and alcohol. Most chose cannabis. Some also opened bars near to their coffeeshops.
Most bars object to weed smoking but there are a few exceptions and these are the smoker-friendly bars. Some are former coffeeshops that have chosen to give up selling grass but still permit smoking. Others were created specifically as smoker-friendly bars.
A few examples in Amsterdam:
Kashmir Lounge was once a nice coffeeshop. After 2007 they took over Jan Piet coffeeshop across the road and gave up the coffeeshop licence for the lounge, which is now a smoker's bar.
