LONDON (KPIX 5) — Hundreds of hungry people lined up when In-N-Out opened a pop-up shop in London.

The double-double and animal-style burgers sold out in just one hour.

“So many choices, and I’m only allowed one, which is a little frustrating,” Gareth Potter, who waited in line for five hours to be first in line said.

So far there are no plans for In-N-Out to expand permanently to England.
