The victims were walking toward their car in a parking garage in the 300-block of East Ohio Street at about 9:58 p.m. when police said five male suspects approached on foot armed with handguns.
The suspects took their wallets and phones as well as the victims' 2014 Toyota Corolla, police said.
One victim was struck in the face with a handgun and treated on the scene by the Chicago Fire Department.
No one is in custody and Area Three detectives are investigating.
