Montevideo is the heartland of retailing in Uruguay. The city has become the principal centre of business and real estate, including many expensive buildings and modern towers for residences and offices, surrounded by extensive green spaces. In 1985, the first shopping centre in Rio de la Plata, Montevideo Shopping was built. In 1994, with building of three more shopping complexes such as the Shopping Tres Cruces, Portones Shopping, and Punta Carretas Shopping, the business map of the city changed dramatically. The creation of shopping complexes brought a major change in the habits of the people of Montevideo. Global firms such as McDonald's and Burger King etc. are firmly established in Montevideo.
