American burger chain In-N-Out will be serving up their unique burgers at Perth CBD’s Market Grounds on Wednesday.

From ten in the morning until four in the afternoon the cult burger franchise are going to be selling the ‘Double-Double burge, the ‘Animal Style’ burger, and the ‘Protein Style’ burger.

Famous for as much as what’s on their niche menu as what is not, it remains to be seen whether the burger joint’s “off the menu” items will be available.

The 74-year old franchise will, however, pull no punches – a poster uploaded onto Market Ground’s Facebook page reads “First come – first served. Limited quantities available”.

“CHANGE YOUR PLANS Cult Burger Joint In-N-Out Burger are taking over Market Grounds tomorrow to make all your burger dreams come true! Check out their page for the deets and #rundontwalk,” the post was captioned.

A promotional event, In-N-Out Burger has not been in Perth for more than four years.

Market Grounds is a pub located on Telethon Avenue in King’s Square. Based in the Perth CBD, it is a short walk from Northbridge, Yagan Square, and the Perth bus port and train station.
