We stopped at this Denny's location before a Pirates game because we had free Grand Slam coupons from a previous game we went to.
It's a small place and was extremely hectic on a Sunday morning/early afternoon. We waited about five minutes for a table. When our waitress came to our table, she saw we had the coupons and just asked us how we wanted our eggs. It was a 15 second interaction. I get they were busy, but she could have been a little more personal.
Food was good! Pancakes, bacon, sausage and eggs all for around $7 I believe if we would have paid full price. Great deal with the size of your breakfast.
I would visit again for their breakfast, but not this location. It seems it needs some renovations to match all of the newer places on McKnight Road.
