Good Eats Near Narbonne High School
Depends upon your price range. The Depot in downtown Torrance is excellent higher end dining, http://depotrestaurant.com/home.html, I hear good things about 1321 Downtown (also downtown Torrance) and it was featured in the LA Times http://www.1321downtown.com/, and Buffalo Fire Department in downtown Torrance http://www.buffalofiredepartment.com/. Also, the food court in Mitsuwa market on Western is a fun place to eat on the cheap.

Depending on the day of the week and the timing I'd try to make the paella extravaganza at La Espanola (all of a mile from Narbonne HS). Even if that's not doable I'd still try to get there for a "Spanish food" shopping expedition.
