How expensive, 17.5 Euros, I remember it seems. But to be honest, it's not expensive for the local people, and it's the money for a meal. The oil paintings inside are still good. You must visit the scenic spots in Holland. Personally, I am a fan of Van Gogh. I don't have many Van Gogh paintings, but it's very quiet. There are many Chinese tourists. Don't miss it when friends who like quiet literature and art come to Amsterdam.
