It was only back in March when I noticed that Asian shaved ice shop Sweet Crush had closed its doors at 11753 San Vicente Blvd. in Brentwood.  Wasting no time whatsoever, Moo Greek Yogurt quickly moved in and threw open their doors this week.  Moo offers a menu of home-made yogurt gelato and yogurt bowls in a variety of sweet and savory options as well as build-your-own.
