In-N-Out Burger is open in Melbourne right now. The American fast-food institution has quietly opened a pop-up shop at 212 Little Collins Street and is serving hamburgers, cheeseburgers and double cheese until 3pm today only (or until sold out).

The go-to burger of the celebrity chef - everybody from Gordon Ramsay to Julia Child, with a bit of Thomas Keller and Anthony Bourdain in between (and not to mention countless movie appearances) – In-N-Out has established a reputation for a loyal customer base and fanatical responses whenever a new store opens. A recent pop-up in Sydney sold out in two hours, so drop whatever you're doing, change those lunch plans, and get your burger on, West Coast style. There are also T-shirts and key rings for sale so you can prove you survived the great Melbourne In-N-Out pop-up of 2014.
