2008_10_shakuws.jpgFrom Shake Shack: "Our official opening day for the Upper West Side Shake Shack is this Monday, 10/20. Shack’s hours on the Upper West Side will be in flux for the first few weeks (11:00 AM - 9:00 PM), but once the Shack is really shakin’, it will be open seven days a week from 11 AM - 11 PM. Our site will keep tabs on any hour changes. Depending on how practice sessions go, Shack may open it's doors to the neighborhood a little sooner than Monday. But the official (read: definite) opening is Monday at 11:00 AM." A few pictures of the UWS Shake Shack in progress here.
