Although the entrance to the metro station is buried underneath rubble, the nearby sandwich shop, Joe's Spuckies, has been turned into a Gunners camp. The shop has two stories: the first story has a front counter with nearby armor and weapons workbenches, several seating arrangements and a kitchen in the back. The second story has more seating arrangements.
Postal Square appears only in Fallout 4.
- Fallout 4 Vault Dweller's Survival Guide Collector's Edition p.492: "[15.08] POSTAL SQUARE
Surrounded by ruined and impassable skyscrapers, this Gunner stronghold is well defended with turrets as the Gunners attempt to knock back Super Mutant incursions to the south, where most of the mines are.
While the Post Office Station is closed permanently, Joe’s Spuckies is open and used as the Gunner’s base of operations. It has a good supply of ammo and Caps."
