Melburnians, I need some local knowledge disco advice. A friend of mine is turning 40 soon, on a Saturday night, and need a place to head post dinner for celebratory shaking of the booty. She wants old school tunes, none of this modern thumpety thump music. Does anyone know anywhere fun, preferably in the inner northside/CBD area which would be ace for someone wanting to return to the dance floor after a significant hiatus and not be horribilised? What's the happs?
