There are Folks in Montreal that think they invented the deli and pastrami LOL
I’m just glad I can get a Rueben in Montreal
Schilo’s Deli San Antonio has a good cheap Rubens and Spaten Optimator on tap served in frosted mugs.
Right next to the USO, just off the river walk.
Dunno who really invented pastrami. But what I’m describing was popularized as a Jewish alternative to bacon.
