Mama Dolce's

 marks Mama Dolce's Food Processing Plant on your Pip-Boy's map in Fallout 3. This place can be reached either through the Flooded Metro Station then east through Arlington Cemetery, or through the Arlington/Falls Church Metro in Falls Church. Mama Dolce's Food Processing Plant is divided into three parts: Between the entry-side Processed Food, and Food Distribution, lies the Loading Yard.
 * Mama Dolce's Processed Food
 * Mama Dolce's Food Distribution
 * Mama Dolce's Loading Yard

Project Invade Mama Dolce's
A terminal in the Food Distribution section can only be used by looting Mama Dolce's Encryption Key from the body of the Chinese Remnant Captain.The terminal reveals that Mama Dolce's was, in fact, a front for Chinese intelligence and espionage throughout the DC area, and would undoubtedly serve as the base of operations for the other outposts scattered in the surrounding Wasteland. It seems that their front, in the end, came back to bite them, as when the bombs dropped they became the Ghouls you fight in Mama Dolce's.

Books

 * Tales of a Junktown Jerky Vendor is outside just north of the entrance behind some barrels, next to a dead Wastelander, in a boxcar.
 * Chinese Army: Spec. Ops. Training Manual is next to one of the snipers in the Loading Yard area.
 * Guns and Bullets is next to the other sniper on the opposite side of the Loading Yard.
 * Guns and Bullets is in a bathroom stall on the ground floor in the Processed Foods area.
 * Dean's Electronics is on a shelf in the middle of a stairway in the Processed Food area; it's next to a phone, a toolbox and a broken computer.
 * Tumblers Today is in the Food Distribution area. Drop down through a hole(s) in the floor to the lower “cave” area to find the book next to two safes and a skeleton.
 * Two Pre-War Books can be found - one is in the Food Distribution area, on an upper level next to a terminal. The second book can be found on/under a small table in the upper level in the Processed Foods area.
 * A sniper rifle and large amounts of .308 ammo are on one of the loading yard balconies (perhaps put there to allow the player to snipe enemies in the courtyard itself). Silently attack the Chinese Remnant sniper up there (Chinese Officer's Sword is perfect), then take out the guy on top of a rail car with a missile launcher.

This is also a very helpful place for those looking to stock up on sugar bombs. As many as ten can be found within the factory.

Misc

 * Nuka-Cola Quantum is on the upper level in the Food Distribution area. It's on a desk next to a terminal.
 * On the ground floor in the Food Distribution area there is a ramp that leads downwards to two safes which require average and hard Lockpicking Skill respectively.
 * Good place to pick up Chinese Assault Rifles, Sugar Bombs, and Books, as well as the otherwise hard to find Dirty Chinese Jumpsuit.
 * Two Stealth Boys can be found in the building. The first is located in the upper levels of the Food Distribution area under the desk which holds the Chinese Commander's computer. The second is in the Processed Foods area through a set of double-doors, located on a table to the right as you enter the room.
 * In one of the two main building contains a Fat Man, but you have to activate 'tcl' in the command console, because the Fat Man is inside the foundation of the building(below the floor you normally walk on). At the same time you can see a some sort radio receiver(same level as the Fat Man)and a connection with one of the radio frequencies you hear when you are outside the Citadel. You can activate it but you can only reply 'See you later'.(Confirmed only for PC).

Bugs

 * Outside the front entrance to Mama Dolce's, there is a (supposedly) dead Wastelander next to a book... Although he appears dead, every several seconds... he blinks! (Confirmed on Xbox 360 and PC).
 * There are radioactive barrels around this Wastelander along with green "radioactive" dust, but there is no radiation.
 * In Food Distribution there are two Very Hard Doors (require 100 Lockpicking to open) that open onto blank walls. These can be accessed by jumping from the top catwalk onto the middle catwalk in the largest room of the food distribution area.
 * Sometimes when you enter the Loading area and kill one of the ghouls, but didn't like how it turned out and then reload your save, you can't move the targeting reticule around. The only way is to reload an actual save like 001 or 1125 to get it back to normal. (confirmed on Xbox 360 PS3)
