It´s been a month since I visited De Os and I can´t remember what we smoked other than a Maroc hash, ice-o-lator and Blueberry, but I can say, hands down that this is the best coffeeshop experience I´ve ever had.
It is located in the middle of the town, but in a secluded area behind the main street. They have a rather large menu of weeds and hash and also plenty of smoking peripherals such as bongs.
What made this shop stand out was the "authentic" coffeeshop feel it gave. Downstairs were a large table for 10+ people to sit at, promoting a social atmosphere. Upstairs had pooltable and plenty of more seats. The music was just loud enpugh for people to have a conversation in normal volume. We ordered a pot of tea (4 euro) and was served at the table, the guy brought us a bloody plate full of cookies for free with the tea and we had a long sitdown in the shop.
Going to Leeuwarden from Amsterdam is a 2 hour train ride. And I must say, it is well worth it for De Os alone
