Prague, Czech Republic
When regular clubs empty out, Studio 54 is just opening its doors. Sort of an ode to the New York original's famed hedonism, resident DJs play tasty dance tracks until three in the afternoon. That's why this is a popular after-hours hotspot for image-conscious locals, hardcore partiers, and club personnel who just got off work. If you want to fit in, just grab a drink, dress to impress, and wear some shades.
