The Rangers capped off a successful season with a day-long team gathering in New York on Sunday.

Following their unfortunate Stanley Cup loss to the L.A. Kings on Friday night, the team -- including Henrik Lundqvist, Rick Nash and Ryan McDonagh -- hit up STK Downtown before going their separate ways for the off-season.

We're told that the gents spent a few hours on the restaurant's rooftop, downing buckets of beer and having appetizers, and then moved downstairs for a private dinner, accompanied by lots of wine.

"They were all smiling, laughing, hugging," a witness said.
