Like to keep track of where you have been? The Visited list allows to mark places you have been to and keep them all in one place. Just tap the 'checkmark' icon to mark a place as visited and it will be added to a list that holds them all. Just like the Favorites list, simply tap the icon again to unmark it.
The Visited list also allows you to send feedback on what you liked, what your favorite dishes were and to let the inspectors know of anything else you feel they should be aware of. Look for the 'Review" button to launch the feedback process.
