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 Falls Church/Arlington Metro Station 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 the security system warns of excessive radiation levels, suggesting that the spies, despite being highly trained, failed to maintain their nuclear-powered machinery and suffered the radiation poisoning that turned them into the Ghouls you fight in Mama Dolce's.

Notes & Bugs

 * 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 kilometers from the actual plant (possible bug?)
 * Despite being Ghouls, the Ghouls will still be hostile to the player if the Ghoul Mask is equipped.

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.
 * Pre-War Book is on the upper level in the Food Distribution area. It's on a desk next to a terminal.
 * Another Pre-War Book is on the upper level in the Processed Foods area on a small table.

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 is 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.
