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 the Ghouls you fight in Mama Dolce's.

Notes & Bugs

 * The Chinese Remnant Ghouls are not feral but will be hostile to the player-probably because the player is "American".
 * 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.
 * In the Loading Yard there is a gate that requires a key to open, but there is no corresponding key in the Mama Dolce's location, possibly because it doesn't lead to anywhere (bug?). The other side of the gate was not intended to be accessed, and the alley is unfinished beyond line of sight. The letters seen on the wall through the fence start at the 'E' in "ERIES". Because of the nature of Mama Dolce's, the writing on the wall probably is "Deliveries".
 * Mama Dolce's Loading Yard is mapped a few kilometres from the actual plant (possible bug?). Fast jump is available from Mama Dolce's.

Books

 * Tales of a Junktown Jerky Vendor is outside just northeast of the entrance behind some barrels, next to a Wastelander corpse.
 * 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 a small table in the upper level in the Processed Foods area.

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 and Chinese Commando Hat.
 * Two Stealth Boys can be found in the building.
 * A Power Fist is in a locked (Very Easy) footlocker in the Food Distribution area just inside of the door to Arlington Cemetery.
 * In the Loading Yard, you can jump from a boxcar onto a large open-topped garbage bin. (Run down the side of the top of the boxcar to jump; don't run across the boxcar's end to jump. The downslope of the roof prevents an effective jump.) The bin has 4 metal boxes and a garbage can, but they only have common loot.
