Loud, sticky Kassen sends livers packing with its dirt-cheap drinks and happy-hour specials (80kr cocktails, anyone?). Guzzle unlimited drinks on Wednesdays for 250kr, with two-for-one deals running the rest of the week: all night Thursdays, 4pm to 10pm Fridays and 8pm to 10pm Saturday. Cocktail choices are stock-standard and a little sweet, but think of the change in your pocket.
Pours are generous and the crowd mixed and fun.
