Die Fledermaus at the magnificent new Operaen at Holmen, in Copenhagen harbor.
Even if you're not an opera aficionado, the theater and its setting are so spectacular, it's well worth attending (if you can snag a ticket).
Fledermaus is a light comedy (operetta by Johan Strauss Jr.) and easily "digestible" - and the cast, from DKT's company, is very good.
