Sagami is a good place for quick Japanese food.  They've got various types of rice bowls and sushi.  It's only takeout but there are tables outside if it's a nice day.   It gets pretty crowed at lunch.  There's also about 6 other takeout places there if you've got a hunger for Japanese food and your friends don't

Directions: Take the 405 south to Culver.  Turn left from the exit on to Culver.   Left at Barranca.  Then left at the next light into the shopping center with a Target and a Mervin's.  It's in the middle.
