Must be the busiest place on earth! Times Square. Everyone is a tourist, apart from the street vendors. You are literally rubbing shoulders with everyone from around the world. Traffic is grid-locked, impatient, with taxi and Uber drivers continually pressing their horns. Madness.

If staying for any period of time in New York, and intend visiting a few tourist sites, such as the art galleries, museums and other tourist attractions, do pay in advance and buy 'vouchers' which you present at the entrance. This way you spend less. Paying at the entrance is quite expensive, with the Metropolitan being $24.
Finding somewhere to eat: plenty of fast food outlets! Not the most health food.
Warning be aware that when you get your bill in a restaurant or café, it will have added to it a 'service charge' which can be something like 20%, plus gratuities (a tip) of another 10 or 15%!
rules differ in different states. In Florida, the tip wasn't included in the bill, but the waitress asked 'do you want to leave a tip?' When we said 'No', her happy demeanour changed dramatically and she flounced off from the table.
