Into the early hours, people are usually out on Karl Johans Gate. Aker Brygge/Tjuvholmen, the wharf area, has many bars and some nightclubs, attracting mostly tourists, couples on first dates, and other people willing to spend extra for the waterfront location. Grünerløkka and Grønland have even more bars, pubs, and cafés catering to a younger crowd. A more mature upmarket crowd ventures out to the less busy west side of Oslo, to Frogner and Bygdøy.
Drinking out can be very expensive, with prices varying greatly (from NKr 37 to NKr 127 for a pint of beer) depending on where in the city you are. Some bars in town remain quiet until 11 or midnight when the first groups of vorspiel partiers arrive.
