Hannekes Boom is one of the nicest waterfront café in Amsterdam to have a beer when it's sunny. Close to Central Station, the place isn't crowded by tourists, but you need to be there early to get a seat.
I love how small this place is, but it offers such amazing quality in cheeses, meats, wines, bread etc. You can also have lunch here. Definitely worth picking up fresh food here!
OT301 is a cultural centre in the former building of the Film Academy at the Overtoom. It’s a good place to get drunk, watch a movie or to eat. It's not too expensive, like most other places in Amsterdam, and the ambience is good.
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.
