Alarming video shows the moment a Melbourne chef unleashed on a customer, trashing their table and throwing them out of the pizza restaurant.

A group of friends were visiting the trendy Italian eatery Kaprica in Carlton in April after the venue had gone viral on TikTok.

One of them was recording a message for their boyfriend to complain about how spicy the prawn pasta was when chef Pietro Barbagallo appeared behind them.

'I literally had like, the chilliest food tonight, and it was so spicy,' the unnamed customer said to the camera in footage first published by Nine newspapers.

Appearing behind them, Mr Barbagallo can be heard saying: 'Really? Really you have to do that?'
