The closest restaurant to UCSB (Goleta) is Beach Side Bar Cafe on the water next to the pier.
It's been there for ages and would be a nice place for you and your daughter to walk afterward.
If you want to travel in to town a nice lunch spot is Olio E Limone.
It's a lovely setting with very good Italian and has its own pizzeria...delicious.
Upper State has a nice restaurant called "Jane"...great salads, soups and a lovely ambiance.
Lower State has lots of Indian restaurants and some are quite good...college students seem to migrate to this area.
Crushcakes (upper State) has a cafe with panini and soups and some of the nicest cupcakes I've found anywhere.
Enjoy your visit.
