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
A sniper rifle and large amounts of .308 ammo is 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 railcar with a missile launcher.
 * 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.

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.
 * 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.
 * Instead of repairing the Chinese Assault Rifles, you can give them to Pronto in Paradise Falls for a 20% discount on a newly expanded inventory. See Economics of Violence for more details.
 * A Fat Man can be found by jumping over the wall between the Food Proccessing and Food Distribution.
 * In Mama Dolces there is a catwalk below you with 2 doors locked verry hard if you open them there will be just a wall behind them(you have to jump from the catwalk your on to the one thats under you).

Notes & Bugs

 * There is a gas leak in the room you first encounter them in, if you entered in the Arlington side. To set it off, you have to be on the top catwalk shooting towards where you came in.
 * When exploring the factory there will be boards with Chinese characters carved on them.
 * 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. 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".
 * Perhaps this spot will be used to facilitate an area implemented in future DLC.
 * This simple exploration can be achieved (without the use of the console) by stacking 2 barrels on top of one another and use one of the barrels as a "step". However climbing the barrels requires some frantic jumping. These images were taken from Fallout 3 on an Xbox 360:


 * Mama Dolce's Loading Yard is mapped a few kilometers from the actual plant (possible bug?). Fast jump is available from Mama Dolce's Loading Yard.
 * On the encrypted computer it can be noted that the food colorant is the same as the printer ink.
 * When entering Mama Dolce's at higher levels (16 in my case), it turns into a good source for high-condition Chinese Assault Rifles
 * In the largest room of the Food Distribution room, there is an average turret control system computer that, after you succesfully hack it, you can select the system information button and it will say things like: "New_Admin: F*CK YOU"
