New York holds firm as one of the world’s priciest destinations for a business trip and as such, it’s worth your while (and your wallet) to mix a bit of pleasure with business. Base yourself in a neighbourhood such as the Flatiron District and you’ll be surrounded by incredible restaurants (try the Japanese fusion restaurant Ferris or get the tasting menu at Eleven Madison Park) perfect for entertaining clients – or catching up with friends. Plus, the boutiques of 5th Avenue right at your doorstep so it’s easy to squeeze in shopping between meetings.
