"Known for its slogan “Katz never klozes,” this deli promises a stacked sandwich at any hour. Visit the longtime Montrose location, or the newer locations in the Heights and Shenandoah, where it's never been easier to score matzo ball soup, French toast, or a pastrami sandwich, 24 hours a day, seven days a week." - Sean Hekmat, Brittany Britto Garley
