Founder Ike Sewell, now deceased, introduced Chicago to deep-dish pizza when he opened Pizzeria Uno in 1943, and it has become the city's signature dish. Pizzeria Due opened a short hop away (at 619 N. Wabash) in 1955 and offers the same menu in a larger space. Many tourists are surprised when they hear their pizza will take a minimum of 45 minutes to prepare, though a sign outside warns them of this fact. An "Express Lunch" is available between 11:30 a.m. and 3 p.m. The room's not much, a total of 18 small tables and five booths, plus an eight-seat bar. (Pizzeria Due is more lavish, and can handle parties of 30-40 people.) The pizza, not the atmosphere, brings 'em in.
