Best brunch I've had in Amsterdam :) Love their bloody mary, and negroni. Also great for dinner!
It's owned and run by Australians so it's super laid back and beautifully designed.
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.
