Uno Pizzeria & Grill (formerly Pizzeria Uno and Uno Chicago Grill), or more informally as Unos, is a franchised pizzeria restaurant chain under the parent company Uno Restaurant Holdings Corporation. Uno Pizzeria and Grill is best known for its Chicago-style deep dish pizza. Ike Sewell opened the first Pizzeria Uno in 1943.
Uno Restaurant Holdings Corporation's child companies include Uno Pizzeria & Grill and Old Chicago
