Zac Efron stopped by Asanebo restaurant yesterday for lunch with a friend. The actor sported a baseball cap as he left the popular Studio City sushi spot. Zac is back in Southern California after taking a July vacation to Saint-Tropez, where he hung out with friends and was spotted lounging shirtless on a yacht. He hasn't been on the big screen since The Lucky One hit theaters earlier this year, but he'll return this Fall with an edgier-than-usual role. The trailer for The Paperboy, which Zac stars in alongside Nicole Kidman and Matthew McConaughey, was released at the start of the month, and the drama promises to reveal a slightly darker, more grown-up side to Zac.
