I’m looking for a movie I saw on late night cable once. It was an 80’s or 90’s movie about a roadside diner. The whole film basically takes place at this diner. It had horror and sci fi elements. People are killed and I think the diner is sort of a nexus where time doesn’t pass. The characters may actually be dead the whole time.
When Strangers Appear (2001)?

“Highway to Hell”(1992)?
It has a diner with people from different time periods and zombies? You can see parts of it in this trailer.
