The restaurant is unique for having a giant bowl sculpture on its roof with a body armor pickup inside it. The restaurant is a destination for Taxi Driver in Grand Theft Auto: Chinatown Wars. The business name appears on some Pony vans.
Sum Yung Gai's building design is based on the real-life Chao Zhou Restaurant at 40-52 Main Street, in Flushing, Queens, which is most notable for its signature red bowl and chopstick sculpture on its roof; the restaurant is based in the first floor, while the second floor is occupied by a karaoke "KTV MONSTER" lounge (The "MEN STORE" sign on the building in-game is derivative of the "MONSTER" sign of the real-life karaoke lounge).

- The name 'Sum Yung Gai' is believed to be a poorly translated Cantonese for 'Three Cup Chicken' (三Sam 杯Bui 雞Gai) which became 'Three Drink Chicken' (三Sam 飲Yum 雞Gai). The poor translation is likely done with intention so as to add a sense of humour for the particular emerging parody in order to make more sense. It could also be a reference to the Thai dish 'Tom Yum Gai'.
- As its name implies, Sum Yung Gai is a phonym of 'Some Young Guy' or 'Some Young Gay'.
- The chopsticks and bowl sculpture on the Chao Zhou Restaurant is considered smaller than the sculpture on the Sum Yung Gai.
- If maneuvered correctly with a vehicle on the subway track, the player can get a car into the bowl without it falling out.
- There is a Sum Yung Gai minigame on Rockstar Games Social Club called Peking Duck Hunt.
- The Peking Duck Hunt mini-game is a reference to two things. The first is Peking Duck, a local delicacy of Beijing China in which a fattened duck is roasted, cut and sliced up, and usually eaten by rolling it in a flour pancake and smothered with spring onions and a sweetened sauce ala a burrito. The second is the game Duck Hunt, the original light gun game from Nintendo.
- If you look carefully at the picture symbol, the picture-gram looks a lot like either a breast lactating milk or a penis ejaculating. This would fit perfectly with Rockstar's humor.
