For me the worst is a three way tie, separated by time & space. Ma's Diner located in the red rock country midpoint between Moab & Monticello, UT was pretty greezie in the late 70's. Ma's is long gone. ACE hamburger in Mizzoula, MT during the 80's/90's was also a caution. ACE is also gone now. And some place I forget the name, between Wenatchee and Leavenworth, WA on the highway up & over Stephens Pass serves up proper stomach churning fare. I may have to give them a second chance at making it right this coming season. There is a strategically placed rest area, 20 miles up the road

The "Best"?, that's like searching for the holy grail, always around the next bend. But you know it's out there
