Hidden in the greenery near Westerpark, the perfect hideaway from street noise can be found if you know where to look: a little farm called "De Buurtboerderij". Surrounded by a bunch of sheep and a happily decorated garden, the restaurant inside serves one fixed menu a week for a low price. The farm serves as community center as well and is run by volunteers — and you when you eat there! — and there are plenty of sweet people and animals to hang out with.
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.
Since I’m a graphic designer I'm obviously into books and my favourite bookstore in Amsterdam is Boekie Woekie. This small shop is located in the Nine Streets and they sell nice and special publications that are often hard to find because they are self published or published by small press publishers. If you are into graphic design you should really check it out.
