Diamond Plaza is Saigon's premier department store. The complex includes a 22-story building and a 15-story building and serves as shopping center, 6 cinema lounges, restaurants, bowling center, a mini mart, cafe and hospital. The complex was completed and open for business in 1999. There is a helicopter pad on the roof of the building.

Diamond Plaza opens at 10:00 am, and are closed to the public on Mondays considering the city's street stalls are busy from 6:00 in the morning. The prices are fixed so you can't bargain, but you will find genuine designer clothes from Vietnamese designers as well as imported brands. The famous brand 'Made in Viet Nam' can be found on the 2nd floor and KFC on the 3rd floor.
