That Cleveland Polish Boy looks really good.
https://en.wikipedia.org/wiki/Polish_Boy
Kinda reminds me of the Detroit Asian corned beef, in that you have a legacy group (Slavs for East Side of Cleveland and Jews for Northwest Detroit) and the newer African American demographic incorporates the legacy cuisine into a new mashup cuisine.
And this is why, in 2021, there are still lots of formerly Jewish-owned delis dotting Northwest Detroit, even though the Jewish community has been gone since 1975 or so. The restaurants, under new, usually immigrant or African American ownership, adjusted their offerings to better serve the newer demographic.
