I tried this a year ago, could not even get near the place. They had college kids and old folks coming in by the busload. Cars parked a half mile back on the frontage roads.
Interesting, headed for the local Perkins instead, found them packed too and in a panic.
It seems like Perkins assumed business would be slow because everyone would be at Dennys so shorted themselves on help that morning. Then because Dennys was a huge overcrowd and so many had their sights set on breakfast out, they amazing overflow headed for Perkins and others and made huge crowds there too. Perkins could not begin to handle the crowd they had and were calling other stores in the area far away from a Dennys to send over more help.
