The Wan Chai Mall is primarily home to the Red Arrow Lucky Money club, and Red Arrow leader, Max Chen.
The other major attraction in the area is the neighboring Quick Stop shop. Inside the Lucky Money an ex-employee tells you the MANAGEMENT/CODE324 password to the Quick Stop computer, giving access to safe. The shop contains multiple resources that can be consumed for health. Entering the shop or destroying the glass will cause all police on the level to immediately turn hostile, even if they were unable to see you inside or if you weren't the one to break the glass.
The mall contains other closed shops that JC Denton cannot enter.
