UNO Restaurants, LLC | 6,455 followers on LinkedIn. Best Food Around! | The Uno® story begins in Chicago in 1943 when Ike Sewell developed deep dish pizza and opened a new type of restaurant at the corner of Ohio & Wabash. It was here that Ike served a pizza unlike any that had been served before. Today, Uno® still draws its identity and inspiration from the artisan heritage of the original.
