Opera lovers pay heed: Poland's Grand Opera, the Teatr Wielki, knows how to put on a show. Performances are always elaborate and sometimes over-the-top huge. Among favorite performances are Zorba the Greek with full choir accompaniment, La Traviata and a fabulous Nabucco. Set designs have been known to be so elaborate that the audience applauds spontaneously upon seeing them! This is definitely a fine night out. Proper dress is recommended.
