Swifty’s is back up to full speed.

The Upper East Side society staple was much mourned when it closed in 2016. But a new Swifty’s — revived at the Colony Hotel in Palm Beach, Fla. — looked just like the old dining room on a recent evening, with Jean and Martin Shafiroff occupying one table, while Peter Brant Jr. and former model Morgan O’Connor sat at another.

Also dining was art collector Beth Rudin DeWoody. On another evening, we’re told Quest magazine’s Christopher Meigher and wife Grace were on the scene, with Jimmy and Lisa Cohen and Averell Fisk at a nearby table.
