i will be in LA this weekend without a car in Westwood (on Tiverton, near the Hammer Museum). Any suggestions about a good spot for lunch on Saturday or Sunday?

Are you going to be at the Hammer? If so, there is a nice place in the Museum itself - the Audrey. Hopefully surfergirl will see your post . . .

From Westwood you can get up to the Getty Center in 10-12 mins on the city bus. The Garden Café at the Getty is good, plus you can visit the museum and take in the views. On Saturday evenings, the main restaurant is open for dinner.

In Westwood itself for lunch consider Fresh Corn Grill, Clementine, Cava, Tender Greens, or Emporium Thai

Skylight Gardens } These two are at the intersection of
Napa Valley Grill } Tiverton/Glendon and Hilgard/Lindbrook.

The Boiling Crab (Cajun)

If you're willing to take a short Lyft/Uber ride, there are several places in nearby Brentwood within a few blocks of each other on Wilshire. Tavern, Toscana, Palmeri, others.

Or perhaps a splurge at the Bel Air Hotel...?
