Any establishment advertising itself as a "coffeeshop" (as opposed to a
café) in the Netherlands is likely to be a place where you can buy and smoke
They are called coffee shops because since they do not have an alcohol serving licence, and most do actually also serve coffee. Coffeeshops are strongly controlled by the government, and any shop selling soft drugs to minors, or selling hard drugs is immediately closed.
Note the Dutch use the exact word 'Coffeeshop'. The translated Dutch for coffeeshop, "koffiehuis", spelt with a k is more similar to what is called a coffee shop in the U.S.
Pot should never be bought on
the street in Amsterdam. The minimum age
for purchase is 18. Coffeeshops can sell up to five grams of marijuana
per person per day.
