The group was together for dinner at a waterfront restaurant called Seasalt and Pepper.
"Lamar was getting a lot of attention from the women in the restaurant and seemed to be really enjoying it," an eyewitness tells Radar exclusively. "But he wasn't drinking and was well-behaved."
Odom's presence with the group also has fans wondering if he's in talks to join the Heat. Kardashian's ex played with the team for one season before joining the L.A. Lakers a decade ago, and he's now a free agent in search of a team.
His appearance in SoBe comes just as his marital split is playing out on Keeping Up with the Kardashians.
