Prague's nightlife offers casual pubs and bars, sophisticated lounges, live music venues and famous dance clubs - something for everyone. The capital's most popular nightclubs are situated right in the heart of Old Town. Note that the custom in Prague is to share tables with strangers if things get crowded. If visitors are bent on partying, Prague has several organised pub crawls that start each night around 9pm. They meet at landmarks like the clock tower, and other central venues around Prague. The city has also become a popular European stag and hen party destination, further fuelling the already lively club and bar scene. Generally speaking, dance clubs in Prague charge admission fees on Thursdays, Fridays and Saturdays, but are usually free between Sunday and Wednesday. For a more relaxed evening, the National Marionette Theatre is renowned for performances of Mozart operas. Classical music lovers will enjoy attending some tremendous venues and experiencing wonderful performances. If their passion for classical runs especially deep, they should ensure that they visit Prague during the Prague Spring International Music Festival, or its counterpart in autumn, when the city comes alive with world-class classical-music performances.
