もうしわけございません。ただいままんせきでございます。もしよろしければ、おでんわばんごうをいただければあきしだいごれんらくできますが。
We apologize. We are fully booked at the moment. If you like, we could take your phone number and contact you when a seat becomes available.
Gesture & etiquette
Point vaguely at empty tables while asking.
Do not try to seat yourself. Do not insist on an empty table if told it's reserved.
