Is there a strict dress code for attending a performance in the Budapest Opera House?
Not really. It is not compulsory to wear an evening dress or suit and tie but if you dont want to stick out, wear at least a smart casual outfit. No one will tell you anything if you are wearing jeans but you yourself might feel out of place. Hungarians are opera lovers since it is part of their cultural heritage. And when it is about going to the opera or to the theatre they know what is right to wear, so they dress up.
