Keystone Corner Lunch serves excellent burgers, fries, and milkshakes, with a wide variety of combinations to choose from. Their shakes, including caramel and mint cookie flavors, are a highlight. The staff are very helpful and friendly, providing a great atmosphere. Food is prepared quickly, and the ability to mix and match menu items is appreciated, especially for those on special diets. With plenty of parking available, this small restaurant is a must-visit for delicious and filling food at a great value. The hand-cut fries, seasoned burgers, and hotdogs are standout options, and the prices are better than fast food. Kid-friendly meals make it a great choice for families.
