December 3, 1948 – Pizzeria Uno opens for business. According to Eater Chicago Ike Sewell worked for Fleischmann’s Distilling Corporation and his future partner, Ric Ricardo, was the owner of Riccardo’s Restaurant and Gallery at 437 North Rush Street. The original plan was to open a Mexican Restaurant until Riccardo, an Italian by birth, tasted Mexican food for the first time. That pointed the duo in the direction of pizza, but not just the usual thin crust of tomato sauce, cheese and toppings, but a pizza that was worthy of the city with the big shoulders. The restaurant was originally called The Pizzeria and then Pizzeria Riccardo. It became Pizzeria Uno when Sewell and Riccardo opened Pizzeria Due a block away in 1955. Today there are over 130 Uno Pizzeria and Grill restaurants in 21states, Washington, D. C., South Korea, the United Arab Emirates, Honduras, Kuwait, and Saudi Arabia.
