A retrieval site (S1) comprises a retrieval server (S1a), a retrieval database (S1b) and a registered fast-food shop database (S1c). Based on a designation entry of a merchandise genre and a destination from an information terminal (T) having connected with the retrieve site (S1), the retrieval server (S1a) retrieves fast-food shops (F), having a service providing area including the designated destination, from the retrieval database (S1b), and displays the retrieved list of the corresponding shops on the information terminal. After a fast-food shop (F) is selected from the list, the retrieval server (S1a) retrieves data of an order form (D) from the registered fast-food shop database (S1c), and displays it on the information terminal. When an order is made based on the order form (D), the order contents are sent to the selected shop.
