Let's study the different parts of this screen.

A tab bar at the bottom of the screen displays Explore and Map buttons. The Explore button is selected, and you see a Collection View displaying a list of cuisines in collection view cells. A Collection View Header containing a LOCATION button is at the top of the screen.

Before you can pick a cuisine, you have to select a location by tapping the LOCATION button.
