Jenever is a traditional Dutch spirit, sometimes called Dutch gin or wodka in English. Wynand Fockink has a distillery and tasting house right at the very hart of Amsterdam. This place is frequented by locals and tourist alike because of their delicious jenever. Be sure to try a glass of Wynand Fockink Superior. If they empty the bottle while filling your glass you're entitled to a so-called 'Amsterdammertje'; you'll have to drink your glass in one gulp and then you get a free refill.
The Bartolotti is perhaps one of the most beautiful Museum Houses Amsterdam has, built by someone who once was the richest man in the city, but it's a bit hidden in plain sight. These days, it is run by a group of lovely old ladies, who can't wait to offer you tea or juice. You can walk around the house like you live there.
You have to ring the doorbell to get in.
