Cooks were grilling breakfast when the grease fire erupted.

“Between the bacon and the potatoes — sometimes it’s a type of little spark, you throw a little milk on it or something and it dies,” said Llanerch Diner co-owner Mike Mihos. “This time, the thing had a mind of its own.”

He says the flames were too intense for the efforts of his employees before actual firefighters arrived.

Mihos explains that they were able to contain the fire, and that it could have of been much worse.

Silver Linings Playbook was done here — that brought people from everywhere, even from around the world,” he said.
