Security was notably tight at the restaurant Thursday night, and actor Edward Norton was reportedly with the group.
Clooney's rep did not deny an engagement to ET, stating, "I don't comment on my client's personal life."
The couple was first rumored to be dating in October 2013. As reported by ETonline last month, Clooney and Alamuddin showed some PDA snapped by photographers while on a private photographic and observational safari in Tanzania with a few friends.
