Earlier in the day, the new mom enjoyed a quieter activity: dinner with five friends at Spago restaurant. The group dined on an array of items, including crab cakes, prosciutto pizza and tuna sashimi. Theron was in Sin City to celebrate a friend's birthday before continuing on her Snow White press tour.
