Souvenir shop introduction: The United Nations arranges guided tours every day, starting from the public foyer of the General Assembly. International staff take visitors to some of the main Council Chambers and General Assembly Halls and explain to them the work of the United Nations and related organizations. The tour also includes visits to artworks and other meaningful items donated by member states. The United Nations postal counter (where tourists can buy United Nations stamps), the United Nations bookstore, gift shop, and snack bar are also located on the public concourse level.
