The "Menu" links for these restaurants showing in the KP are linking to the incorrect restaurant in the chain.
Each restaurant is on its own sub domain, with clear structured markup, so Googlebot should not be getting confused between who`s menu is who`s.
One Example
https://plus.google ( dot ) com/110240171749822543608/
Business name: Firebirds Wood Fired Grill
Website for the one example: http://chadds-ford.firebirdsrestaurants ( dot )com
Any ideas as to why Gbot is getting confused ?
