You’d enjoy the Mayberry Days Festival in Mt. Airy, NC, then. There’s a real Snappy Lunch and a real Floyd’s Barbershop, among other landmarks from Andy Griffith’s childhood and young adulthood there. The Snappy Lunch certainly predates the tv series, it’s sort of a dive but the pork chop sandwiches on white bread rule, lol.
Goober was ok, the replacement deputy is the one I never liked. Forget his name...
If anybody’s curious about Mayberry Days or interested in attending:

How about Mayberry in Star Trek?
