Favorite local restaurant?

Wow, hard to name just one...lots of great places here in Orange County

Mexican - there are two in old town Placentia that are really good but we prefer 'El Cantarito'. Not fancy but excellent traditional 'South of the Border' food.

Ribs & BBQ - 'The Tulsa Rib Company' in Orange. Again, not fancy but outstanding baby backs and big beef ribs and their "Tulsa Potatoes" are special.

Burgers & Stuff - You can't beat 'Heroes' in Fullerton. Our favorite bar and we don't drink! Huge portions of really great food. We've gone there for dinner if we're not super hungry and split a half-order of nachos and not been able to finish it.
