Ade takes a ride in a yellow cab and discovers that a taxi license can cost up to $1 million. Dan Snow heads to Times Square to discover how the 230 LED advertising hoardings are maintained.

In the second part of this new series, which takes viewers on an immersive trip to New York's most iconic locations, presenters Anita Rani, Ade Adepitan, Ant Anstead and Dan Snow reveal the astonishing daily systems that allow America's biggest and busiest city to function. In this episode the team look at food consumption. From their base at the New Fulton fish market in The Bronx, from dusk until dawn, they uncover the hidden night time operations, hard-nosed negotiations and price fluctuations of this enormous wholesale operation.

The team also reports on the revolution overtaking New York's food-delivery networks, as cameras follow the takeaway delivery drivers responsible for getting 180,000 chicken wings to hungry New Yorkers in one night. New York is a city that chooses convenience over home cooking, with businesses adapting to new technology and long-running restaurants using mobile apps - it's another example of a forward-thinking city responding to changing demands.
