If you crave nightlife and love music, be sure to check out Tygmont Jazz Club while you're in Warsaw. This dark and smokey live music venue, open to 4 or 5 a.m., is a mainstay for jazz enthusiasts and international jazz musicians. Relax with a drink (or two or three) and order a snack. Even if the jazz served up for the evening isn't quite your thing, you'll still appreciate the zeal with which other audience members enjoy the music. Be warned, though, that you may be asked not to speak during certain performances. This is par for the course at Tygmont. Trendier jazz clubs in Warsaw may not have such restrictions, but neither will they cater to serious crowds like those at Tygmont.
