This is the best place to get a burger, fries or shakes in the vicinity. I personally like their caramel shake but did try their mint cookie shake on my last visit. Service is friendly and food is made fast!Parking: Plenty of parking with good access.

Ordered lunch today for a group and had it all on a paper and handed it to them. They forgot about my order, had to call. It was nice of them to personally deliver it, that's why I gave 2 stars instead of one, but it waz a Buffalo chicken wrap and it was cold, as in refrigerated chicken not even luke warm. And too spicey. I got rid of the cold chicken and had a lettuce wrap

What a gem to find! We simply googled Burgers and the 4+ star reviews brought us in. Think 5 Guys but OH SO MUCH BETTER & CHEAPER!!! So many choices to make the burger or dog of your choice or choose a creation of theirs. Only issue is that there are very few seats. But I would guarantee take-out would be amazing as well! We had a double burger and fries topped with bbq pork, cheese, sauce, bacon, and more!

Stopped here tonight by chance. We were in the area and normally will go to another establishment. We never knew this place was here.Checked Google and found Keystone Corner. I tell you what, damn glad we chose to come here. The entire staff was super friendly, the diner vibe is perfect and the burger was the best I’ve had.It was just hitting on all cylinders. Moisture was spot on, flavors were perfect. Everything just worked perfectly together on it.The fries were also superb. Crispy, soft in the center. I was also happy that the fries kept their crisp outer shell even while being covered in all the great toppings.I recommend giving this place a try if you are in the area. Will definitely be returning customers when we come back through here.

Food is really good tasting. Their menu is very open. Service is always very good with a smile. They got some old games such as a Pac-Man machine game to look at.

It was the best gluten free hamburger I have had. We shared an order of loaded French fries with cheese, sauce and chives. I will be back.Dietary restrictions: They have gluten free options.
