Entry was free. Note that almost all the houses are open only on summer time.
Great place with fun concept. You need to use an app to order, because we're tourists tha app didn't work for us but the staff were super nice and took our order. The food was nice, a bit greasy.
Interesting museum with Zorn's paintings. There are two tickets - one for the museum itself and one to the tour on his house (note that the tour is only in sweden). The house was very impressive and interesting.
