Is Kiriko too far? If you’re OK for Sawtelle Japantown, might as well do the lunchtime Platinum Bara-Chirashi at Sushi Tsujita.
In Beverly Hills, Sasabune on Olympic Blvd. is no longer serving loosely packed hot rice (at least in the BH location), so that’s a possibility.
Sushi Sushi on Beverly Blvd. is meh for lunch, IMHO. But it’s there.
Happy hunting.
