PENNSYLVANIA, WE HAVE A TOP 10 BURGER. 🍔🔥

Keystone Corner Lunch just landed at #9 on the list of the best cheeseburger spots in Pennsylvania!

#9.

NINE.

Out of the whole dang state.

We’re a little restaurant in Saint Marys making burgers that apparently got noticed all the way across Pennsylvania.

That’s pretty freaking awesome.

Thanks for eating the burgers. Thanks for telling your friends. And thanks for helping us make this happen.

#9 today… but we’ve got our eyes on the other eight. 👀🍔
