My husband and I like to try diners all over Pittsburgh and McKeesport. We absolutely loved Di's Kornerstone Diner! From the delicious food to the friendly service, this will be a definite repeat for the both of us. Thanks again to the awesome staff for making our visit memorable.
Great atmosphere. I love the music choice. Something you dont hear everyday, or even listen to on your own. Loved it. 10 out of 10 gonna go again.
I ordered their country breakfast, which included two pancakes. I have never seen such huge pancakes! Covered my plate! I could only eat half of one. This morning I finished the other half. And that was the small one of the two! Eggs, bacon, and toast were done to perfection. We’ll be back!
Good, local, easy going place to have a yummy breakfast.
