Custom Virtual Tours.
By having a reservation button on your Google My Business (GMB) page, you are already pushing your future customers in the right direction and are helping them do exactly what you want them to do (book a reservation). Google shows that by adding a virtual tour to a GMB, businesses see an average of 85% increase in their online booking.
The hypothesis is that you are helping your visitors better understand your store by showing the global ambiance through your virtual tour. Your visitors are then more likely to book directly from the GMB page since they are already on it.
