Blame Hurricane Sandy or blame the economy, but downtown venues the Windsor and Winston’s Champagne Bar are looking to move north. Winston’s, which is owned by Provocateur proprietors Mike Satsky and Brian Gefter, has been bought out of its space at the Gansevoort Park Avenue. Satsky and Gefter are looking to move their lounge to the Upper East Side. Replacing Winston’s at the Gansevoort will be another outpost of Windsor, the popular West Village sports bar owned by the Lion and Crown partner Sean Largotta and others. The Windsor will likely move into the space by the end of the year, and is also looking at expanding to another location uptown.
