I grew up near HoJo’s biggest restaurant. Too posh for our family to eat there, but Mom and her friend would occasionally take us kids there for cones in late 40s/early 50s.
“The Queen of the Chain” advertised as the world’s largest roadside restaurant.

OT, but possibly of interest... the cupola atop this HoJo appears to be copied from the tower at the older, nearby Newtown HS
