What do you do in this situation of children behaving badly?

You are in a white tablecloth restaurant and your entree alone is going to set you back more than $20.00 (not including drinks, appetizers, salads, etc.). There is a segregated room for a larger party and it is full (with periodic clapping coming from the room). The children of the people in the room are, unsupervised, at a booth and a table in the main dining area. There are about 20 children of various ages. One of the little boys (about 6) is literally climbing into seats, across the tables, and up and over onto the next table. Other, slightly older, boys are running up and down the spaces between tables.

The owner of the restaurant comes over to you and apologizes. All the customers in the dining room are staring at the table of unattended children, but the restaurant owner does nothing about the problem (merely apologizes to the other customers).

Would you take any action? What action would you take? Would it make any difference if the party is clearly Muslim? Would your actions change if you were male vs female?
