The Bronx Deli opened August 2007 in Pontiac at a 1500sqft building located across the street from its current location. The home of the our award winning Big Mouth corned beef sandwich is now located at 247 S Telegraph, Pontiac Mi. The Bronx Deli brings the Detroit area the freshest corned beef and pastrami – and lots of it – on fresh bread. It’s a lot of food, and now it’s in your backyard.
