It was date night for Jennifer Aniston and her on-again boyfriend, John Mayer. The couple were spotted at trendy Mexican restaurant La Esquina last night in Manhattan. Maybe they were celebrating Jen’s guest turn on 30 Rock (or her explosive interview with Vogue), but according to an eyewitness, the duo couldn’t keep their hands off each other. After dinner, they danced the night away at GoldBar. Sounds like a great date to us!
