Thanks to the exchange rate, many Americans have found starting a business in Buenos Aires optimal. Already I can name a few businesses in Buenos Aires, Argentina that were started up by Americans (from the USA) looking to start a business where the exchange rate was in their favor.
Businesses like the California Burrito Company mimic the restaurants from back in the United States.
Or there is the restaurant the Alamo which plays Beer Pong in the United States fashion. Girls love it because the drinks are usually free for them.
Or there is the Sugar Bar an American restaurant and club that was started in Buenos Aires, Argentina.
In the end, the owners moved down to Argentina to enjoy the better exchange rate and start a business with a lot less investment than would be required at home.
