ViVa (Viaduct Valley)

ViVa (Viaduct Valley) is the small but emerging West Harlem area,

http://en.wikipedia.org/wiki/Manhattanville
Manhattanville is the part of Manhattan in New York City bordered on the south by Morningside Heights on the west by the Hudson river, on the east by Harlem and on the north by Hamilton Heights and Washington Heights. Its borders straddle both sides of West 125th Street, roughly from 122nd street to 135th street and from the Hudson river to Saint Nicholas Park.

The park, which will consist of multiple piers and ferry landings, stretches from 125th St to 132nd Street and will fill in one of the few missing links in a cycle and walking path that stretches the entire circumference of Manhattan. Construction of the park is expected to be completed by spring 2007. The emerging area that surrounds the park and piers is often referred to by its neighbourhood name of ViVa (Viaduct Valley)

Retail, Restaurant and Office space available in 2-level historic 1926 freight house restored into a loft-style building."

Predictably, real estate agents have created a name for the tiny neighborhood: ViVa, for Viaduct Valley, evoking the ornate arched bridge supporting Riverside Drive, which was built in the late 1800's.

28 June 2006, New York Post, pg. 40:
As for ViVa -- a k a Viaduct Valley -- that's real estate speak for the West Harlem area reportedly poised to spawn its own restaurant scene in the coming year near Dinosaur Bar-B-Que, Fairway Market and the new Citarella. "New Harlem" is fast becoming the next destination for fine dining.
