Chicago's O'Hare International Airport is divided into four terminals, with terminals one to three located around a central hub of parking garages and terminal five in a separate location. There is no terminal four. Terminal five serves the majority of O'Hare's international flights. Terminal three is the largest of the four terminals and provides most of O'Hare's domestic flights. Terminals one and two are much smaller, each serving just a few specific airlines.
O'Hare provides a shuttle service between the various terminals for quick and easy transfers. Each of the four terminals is equipped with restrooms, lounges, restaurants and shopping. Other services include electronic device charging stations, ATMs, currency exchange offices, and shoe shines and repairs.
The restaurant and bar offerings vary between terminals but typically include both quick and full service restaurants, wine bars and beer bars. Shopping options also vary between terminals and include both duty-free and traditional retail stores selling books and magazines, clothing, electronics, gifts, travel-related items, and Chicago-themed souvenirs.
To help travelers relax, terminal one offers a day spa. Terminal two houses a health club and a barber shop. In terminal three, travelers can enjoy two day spas and a yoga room. Terminal five has an express spa for those in a hurry.
