For the ultimate experience in big city life, car hire in Chicago will give you easy navigation to fit everything into your trip. The city is known for its deep dish pizzas, which are believed to have originated at the Uno Chicago Grill; the crust is up to three inches deep, and served with masses of cheese toppings. Amongst the many Chicago landmarks is the Chicago Water Tower. It now hosts the Chicago Tourism Office, but its historical use was that of pumping water from Lake Michigan. The tower is now dwarfed by surrounding skyscrapers, standing at 154feet tall.
