Time Out says
City Hall ain't big, but it is popular. The music is mixed, from deep house to electro rock, and there's an older post-(pre-?) work crowd joining the young, tanned and skinny to show the dancefloors some love. Outside, the terrace is a melting pot of tourists and locals, who rub shoulders under the watchful (and anti-pot-smoking) eye of the bouncer. Flyers for City Hall are easy to find in bars and shops around town, and will get you in free.
