There are a bewildering variety of pubs, clubs and restaurants in Krakow - unofficial stats claim there are around 400 bars and clubs here. They are concentrated largely in two areas: in the biggest market square in Europe and in the old Jewish district. But it’s not only the amount of clubs and bars, but the fact nightlife here is vibrant 6 out of 7 days week. This is due to a very large student population (over 10 universities) that keep parting most of the week.
