Inside the mess hall the Courier can find the Boomer munitions manager's store at the north-west end of the hall way, the player can find various explosive weapons such as mines, missile launchers etc, inside the store. Near the west entrance the player can find a door to some Boomer chefs inside a kitchen. At the middle of the hall the player can find the tables and chairs, as well as several Boomers eating. A couple of VR pods. similar to Fallout 3 's Tranquility loungers, can be found at the southern part of the mess hall.
Inside the Boomer munitions manager's store at the north west end of the hallway a mini nuke can be found in a box on the the top, right hand shelf at the back. The player needs to be hidden as the mini nuke needs to be stolen.
Near the western end of the building, there are many ammunition crates that primarily house missiles. A player can loot well over 100 missiles, provided they remain hidden (which isn't that big of a challenge, since the crates are secluded). The crates also contain various other kinds of ammo and grenades. (Note: as of v140525, it's possible this place is changed. One game find about 15-20 missile here with various ammo, not hundred like before.)
