Comment(by mikeschinkel):

 So, in the interest of bringing it full circle for others wanting to solve
 this problem (and hopefully for the core team to analyze and address to
 enable others in the future to deal with this in an easier manner) here is
 the code to make the menu and location pages only display one record:

 {{{
 add_filter('parse_query','tyc_parse_query');
 function tyc_parse_query($query) {
         if (isset($query->query_vars['restaurant-dummy'])) {
                 $restaurant = get_page_by_path($query->query_vars
 ['restaurant-dummy'],OBJECT,'restaurant');
                 $query->query_vars['post_parent'] = $restaurant->ID;
                 $query->query_vars['restaurant'] = $query->query_vars
 ['restaurant-dummy'];
                 unset($query->query_vars['restaurant-dummy']);

                 // Not sure if I really need to update ->query, but why
 not? Some plugin probably uses it.
                 $query->query['post_parent'] = $restaurant->ID;
                 $query->query['restaurant'] = $query->query['restaurant-
 dummy'];
                 unset($query->query['restaurant-dummy']);

         }
         return $query;
 }
 }}}

 '''NOTE:''' After editing the slug but before pressing publish the "View
 Location" and "View Menu" buttons don't work for Restaurant Location and
 Restaurant Menu, respectively. Ideally if this gets addressed in core they
 would be disabled or their hyperlink modified after clicking "Ok" to save
 the slug.
