The Fondation Beyeler museum of contemporary art in the Northeast suburbs of Basel boasts an insanely popular special retrospective exhibit on the world famous artist Yayoi Kusama. I am a fan of her work and would love to experience this with some fellow travelers or locals. Wednesday the museum is open longer in the evening which adds a nice vibe. Tickets are 25 CHF I think, but if you are under 25yr it's free. Whoever would like to can join for a drink afterwards!
