Adair’s Tropical Cafeteria, OK City, OK. “One of the fine Adair family cafeterias.”

Note the remarkably untropical exterior. It’s almost anti-tropical. The drapes suggest they've closed down for the weekly Black Mass blood rituals. Or, it's summer, and the afternoon sun is too punishing. I'd go with the former, Occam's razor and all.

Gone now - but the sign next door keeps the era alive. For now.
