Which terminal at O'Hare features the largest number of shops and restaurants?

The correct answer identifies Terminal 1 as featuring the largest number of shops and restaurants at O'Hare Airport. This terminal is designed to accommodate a high volume of travelers, particularly those flying with United Airlines, which is a major airline operating at O'Hare. Consequently, the amenities have been expanded to include a wide variety of dining and shopping options to enhance the passenger experience.

The presence of numerous shops and restaurants in Terminal 1 serves not only to provide travelers with the opportunity to purchase items or enjoy a meal but also reflects the terminal's role as a bustling hub within the airport. This array of options can make the terminal more comfortable and enjoyable for travelers who may have longer layovers or those looking to grab a bite before a flight.

The other terminals may have notable amenities but do not match the extensive offerings found in Terminal 1, catering specifically to the needs of a significant passenger load.
