I think this place is worth visiting. I only entered the upper part, but I think its enough, since the famous artwork 'The Kiss' is located there. To be honest, when I saw the real artwork, it looks not that amazing as other visitors describe. But overall, the whole venue is worth visiting, since there is still a lot of iconic artworks symbolizing different periods of art history. Also, the view of looking outside from the gallery and looking towards the whole gallery are both impressive.
