Of course the audience dresses also here only in the finest evening garments and gets taken away by Verdi, Rossini, Strauss or Mozart. If you want to give your special someone a cultural suprise, get tickets to one of the finest performances at the Staatsoper. Don't tell him or her anything about the destination of the evening, just have elegant as dress code for the night. Then immerse yourself in the performance of "La Traviata" or "Cosi fan Tutte". The nice opera atmosphere will certainly provide for a wedding anniversary to go down in history.
