Diamond City market
The bazaar of the Jewel of the Commonwealth, Diamond City Market has everything anyone would want to buy, including weapons, armor, food, medicine, chems, junk, a new haircut... or even a new face.
The market is situated around Power Noodles, a café. From the north side and looping clockwise around Power Noodles is a bounty board next to Swatters (baseball bats and accessories), Commonwealth Weaponry (weapons), Diamond City Surplus (junk), Home Plate, Chem-I-Care (chems), Mega Surgery Center (medicine and facial reconstruction), Choice Chops (meat and only meat), Cathy & John's Super Salon (haircuts), and Fallon's Basement (clothing).
Diamond City Market appears only in Fallout 4.
