I agree with TS.
Denny's has rolled downhill in the last few years.
They join Waffle House & Perkins. The quality is way, way off.
IHOP is still okay but I'm sure they'll drop too.
I'd add that stories of dumb stick-up men or armed robberies of cops are common. The worse was a article by Massad Ayoob where he documented a hotel convention room filled with LE officers was stormed by a group of hapless robbers.
