"OpenTable" is a service that allows you to make restaurant reservations in real time for free. You can access the site from your computer or smartphone and make restaurant reservations "anytime, anywhere, easily".
The Christmas dinner special page contains information on special menus and services offered by OpenTable member restaurants for Christmas. For example, it is possible to narrow down the search by area, cooking genre, budget, etc., which restaurant has vacant seats on December 24th on Christmas Eve.
However, the basic etiquette is that men make restaurant reservations. If you're reading this, please tell your boyfriend or husband about the service casually.
