De Waaghals (= The Dare-devil) is a very nice vegetarian restaurant. The atmosphere is informal, but the food is very nice, refined and creative. Organic ingredients are used as much as possible. Each month a dish focuses on a different country.
Not a big fan of zoos and animals behind cages, but if you can spot Flamingos in the east-centre of Amsterdam, then count me in <3 ! You can actually see them while riding the bike on Plantage Middenlaan, quite a beautiful scene.
Note: De Plantage next to zoo is quite cool cafe/restaurant, with a mix of vintage style and industrial elements of the old buildings of Artis. Great atmosphere, and ideal for a more sophisticated outing.
Her I enjoy the quit and concentrated atmosphere. I go to the library if I need some new input or just want to work somewhere else than in my studio. You can also just go there to relax at one of the beautiful spots in the building. Or have some food at the top floor with a beautiful view over Amsterdam.
