Zac Efron, dining with High School Musical costar Corbin Bleu and a few other guys at New York's Cafeteria. They sampled items from the menu and had a few mojitos and carafes of Cafeteria cosmos. "Zac and Corbin were totally chill normal people," an onlooker said of the Charlie St. Cloud star and his friend, who got plenty of attention from fellow diners. "They were cool about taking pictures and meeting people."
