ON A QUEST FOR FOOD

Dewar’s 25 saw a slew of celeb visitors swing by its launch party at Blue Ribbon Brasserie — and some of them even meant to be there. We’re told that and wife as well as musician all stopped by the SoHo eatery for dinner, only to be told that for the first time ever, the venue was closed for a private event. Cohen was with O’Connell and Romijn, who’d just finished taping a segment of “Watch What Happens Live,” we’re told. They were diverted to nearby Blue Ribbon Sushi while the whiskey brand continued its celebration. We’re not sure where Questlove (above), the Roots drummer, wound up.
