If the list of Polish celebrities and the length of the queue out front are anything to go by then Van Diesel is the ‘in’ place on Poznan's market square. Negotiate face police to discover a more mature crowd than in most Poznan nightspots grooving to a mix of the classics from the 70s through to the present day. Women get in for free on Fridays and until 23:00 on Saturdays (there after it's 10zł) while fellows pay 10zł on Fridays and 20zł Saturdays. Alcohol is half-price on Thursdays until 23:00 (a day everyone gets in free) and until 21:30 on Fridays and Saturdays. Only open three times a week which is just as well really.
