Victoria Police said offenders rammed the entrance of the Electric Bar with a white Mercedes about 5.40am.
Police said it appeared the offenders may have been disturbed by someone and fled the scene.

An hour earlier, just a block away from the bar, police arrested five people in an allegedly stolen car in which two jerry cans full of petrol were also found.
Officers from the Public Order Response Team who were on patrol in relation to recent hospitality arsons spotted two people in hoodies in Greville Street.
The officers followed them to St Edmonds Road, where they approached a Mazda CX9 with three more people inside.
The vehicle was confirmed as stolen and had false number plates.
Police arrested four males, three of whom were aged 16 and one aged 19, and a woman aged 20.
Investigators say, at this stage, the arrests are not being treated as linked to the incident at Electric Bar but will be reviewed in relation to the current series of hospitality arsons.
