Food fanatics, stop what you're doing and listen up.

After months of speculation, the burger gods have finally granted Dublin its own In-N-Out branch, on Millennium Walkway.

The good news? It's open. Now!

The bad news? It's a pop-up at Vietnamese restaurant Bread n' Bones and will disappear forever at 3pm.

In-N-Out Burger has something of a cult status in the US, as it has branches in just five states.

The chain is known for its simple but seriously tasty menu, serving just burgers, cheeseburgers, shakes and fries. 

Fast-moving Dubliners have already made plans to get to Millennium walkway for the most sought-after lunchtime meal of all time:

So In-N-Out is in Dublin for one day only? Currently plotting how best to reschedule my day's work and make into town before 3pm.
