If your restaurant has an area that will only seat large groups, for example, a private function area, you can control the smallest table size required to open this area to bookings.

In the example above,  the function room will not be able to take any bookings (widget/telephone) with less than 10 covers, and the terrace will not be able to accept bookings less than 12, however, the main restaurant has no minimum covers and will accept any booking as per the settings in place.
