Utilizing clients details on booking platforms like Chope or OpenTable allows you to send booking reminders to guests - it also offers an easy option for guests to cancel. This reduces no-shows dramatically by making it simple and less embarrassing for guests if they have a change of plans.
But if you’re a popular restaurant with a modern clientele then dropping the need to make a reservation during peak times guarantees no no-shows! It’s a brave move and many restaurants are afraid they will lose guests - but offering reservations at less busy times can redistribute your peak times and reduce costly no-shows.
