The westernmost district of New Reno is the West Side, also known as the Commercial Row. It remains under Salvatore protection, although, due to the presence of New Reno Arms, all mobsters are welcome, long as they behave themselves. The district itself is fairly intact, compared to most of New Reno, in addition to being home to some of the more reputable sites of the city of sin.
The most important site is, of course, the aforementioned New Reno Arms weapons shop, where Eldridge runs a mafia supply depot, complete with a wide array of weapons and ammunition and the occasional upgrade, courtesy of the savant Algernon roaming around in the basement. Second is Renesco's Pharmacy, where drugs are on the menu, in addition to skill books and the occasional first aid kit.
Last, the Drunk Cupid Chapel is important, for it is the only place in New Reno where one can obtain spiritual guidance, of the non-sexual, non-drug type, albeit with an alcoholic taste and smell.
West Side appears in Fallout 2.
