In the covered Wanha Kauppakuja laneway, off Aleksanterinkatu, this terrace, or 'tunnel' (it's locally dubbed 'Mummotunneli'), has several bars that turn into a party scene once the restaurant terraces are done with serving food for the night. DJs and live bands rev the crowds up every night. On Friday and Saturday there's a €10 cover after 9pm.
