Pretty much this.
I wouldn't say it's all clout though. Young folks just want a popping place that's upscale and fun. Only folks that go to Denny's are 60+ yr olds.
This is what the inside of a Denny's looks like. Who wants to eat here?
This is a casual cool vibes breakfast joint
I don't even know if it's that as much as the FOOD is terrible at Dennys.
For example, how do you mess up a hamburger or cheeseburger?
The bacon isn't good, the eggs aren't good etc.
