The old school kosher Jewish delis are disappearing. My grandmother would take me to one as a kid where she lived in Brooklyn and I’d get belly lox on a bialy and she’d get a tongue sandwich (never tried it but I’ll admit it smelled good). We would then split a black and white cookie down the middle. I liked vanilla and she liked chocolate so it was perfect. A lot of them have closed as tastes have changed and younger generations don’t want to take them over. Who’s eating tongue, borscht, matzo ball soup, derma, stuffed cabbages, kugel etc anymore.
