How create a community for a Restaurant?

You can do so by creating a community at https://tribe.so/create/3, once you have you customize the community as a restaurant theme-based community. You can use CSS8 if you cannot customize some areas such as making a user's banner parallel or want to customize the post's background color. If you would like to announce any offers or anything else, you can go to Admin >>> Announcement. You can even add a new sidebar section with a "Order now" button and add JavaScript.
