A poster on the LA board asked about East Coast style diners in LA. I wonder, when I think of places that serve "Diner " food, institutions such as "Delores", "Raes", "Panns" etc, they are "Coffeeshops" . How are "Coffeeshops" and "Diners" similar, how are they different? They serve many of the same foods. Is a"Diner" a place evolved from roadhouse, truckstop, early 20th century working class roots? And is "Coffeeshop" more of suburban, leisure class,idea?
