How can I visit another player's Town?

There are a number of ways to visit another player's games and check out their Tasty Towns.

Tap on the Friends icon. The Friends bar lists all your friends and friend suggestions. Tapping on any of the profile pictures will take you to that player's Town.
Tap on the Chef Club building and visit a town of a member of your Chef Club, or tap the Search tab and visit a member of any other Chef Club. Tap on the profile of the player and a Visit button will appear.
