The Sherman Oaks Galleria is a great spot. They have music bands that play on the plaza. It's fun to walk through, pretty water wall, water fountain and gorgeous architecture throughout is very relaxing.
They have decent food selection El Torito Grill, Cheesecake Factory, PF Changs as their other higher end corporate restaurant. There is an Arc light theater and shops as well.
