In the 1990s, local and foreign investment led to a massive regeneration effort, recycling and refurbishing the west side warehouses into elegant houses, offices, lofts, private universities, luxurious hotels and restaurants that conform to a gallery of options for this new district in a city that grew up turning its back to the river. Led by the 1999 opening of the Hilton Buenos Aires, luxurious hotels, state-of-the-art multiplex cinemas, theatres, cultural centres, and office and corporate buildings are located mostly in the east side.
