i disagree with you except you talking about macdonalds,kfc and fast food restaurants that are always full to the brim in the westernworld.i guess you do not understand the concept of table reservation infact Nigeria local restaurants are always full especially in the evenings but they are very disorganized and chaotic and expensive to educate local restaurants owners and users about the service,so it will work well with upscale and medium restaurants in Nigeria, if you talking about local restaurant they are plenty but middle and upper scale restaurant are not much that is why i wrote that the market is small.
open table can work in africa and infact in Nigeria . open table doesnt solve first world problem,it solve world wide problem of booking management and table reservation infact south africa,egypt,morroco,kenya has more organised restaurant system than Nigeria,they are all tourist countries and have a large restaurant industry
the concept works like this
Opentable allows users to search for restaurants and reservations based on such parameters as dates, times, cuisine, and price range. Users who have registered their email address with the system will then receive a confirmation email.Users can also receive 100 or 1,000 OpenTable rewards points after dining; these points can be redeemed for discounts at member restaurants
The service provides restaurant owners with comprehensive reservation management. Subscribing restaurants use an Electronic Reservation Book (ERB) to replace existing paper reservation systems; ERB is an integrated software and hardware solution that computerizes restaurant host-stand operations. The ERB handles reservation management, table management, guest recognition, and email marketing.
