|Not to be confused with The 69th Street Diner, another GTA IV diner.|
These places are inaccessible to the player. However, the player can take a friend or girlfriend on a date there. These diners are a good choice of eating venue when on dates with Kate. The name sounds like a pun of "69-er" (sixty niner), which in turn refers to the 69 sex position.
The exterior of the 60 Diner in Westminster looks similar to 69th Street Diner in Hove Beach, Broker. There is a door at the front and a sign above it that says "60 Diner". Its shape is a lot like a giant trailer from the outside.
In GTA Chinatown Wars, the diner is inaccessible for the player.
