Chinatown is a working residential neighborhood packed into a three-by-four-block rectangle, roughly 7th to 11th and Arch to Vine, with the densest stretch around 9th and Race. It has been here since 1871, starting from a single Chinese laundry, and it's the oldest Chinatown on the East Coast. The forty-foot Friendship Gate at 10th and Arch, built by artisans from Tianjin in 1984, marks the entrance to a grid of restaurants, bakeries, grocers, and herbalists where the primary language on the street is Cantonese and a full meal costs what a latte does elsewhere. The homes are studios and converted lofts carved in above those kitchens, plus a few high-rises out toward Callowhill.
We clean those apartments, including the small studios and lofts over the restaurants. The thing that makes the food here worth the trip is also the cleaning problem: cooking grease, roasted-meat smoke, and market air work into every surface in the building.
