According to TMZ Sports, Odom was with friends and got into an argument with another group. A member of the second group fired a gun into the air without hitting anybody at the restaurant.
Authorities don't suspect Odom of any wrongdoing, and police are looking for the shooter, who fled the scene shortly after the incident.
Odom spent 14 years in the NBA, seven of which came with the Los Angeles Lakers. He helped the Lakers win back-to-back titles in 2009 and 2010 and was the NBA's Sixth Man of the Year for 2010-11.
Odom, who last played in the NBA in 2013, told TMZ Sports in April he was looking to return to the court with a team overseas.
