Fiore's House of Quality • 1913

Since Alphonso Fiore opened his Italian deli in 1913, the roast beef and mozzarella sandwich has drawn lines around the block. Available only Thursdays and Saturdays, the hero stacks tender roast beef with housemade mutz and brown gravy—Frank Sinatra once had it flown to Las Vegas. Come early, bring napkins, and prepare for the most gloriously messy sandwich you'll eat.
