The ability to see the city of any person in the app is available to Premium and Premium GOLD users.
If you're ready to purchase a subscription, go to the profile of your potential match, tap "See his/her location," choose the subscription period, make the payment, and you will be able to see the location of any person.
If you want to see people from a specific city (e.g., New York), go to the Search section and tap on the icon with sliders in the upper right corner — specify the city and see suitable people from there.
