I don't think he's gotten it going yet. When I talked to Omar in April, he was thinking of using the space in Wicker Park that John Bubala was using for Baccala. However, he had just learned that John was keeping Baccala open. Now that Baccala has closed, perhaps Omar can get hold of that space for KNEW.
However, I would recommend to Omar to not go to Wicker Park, because I don't think that area will support fine or semi-fine dining. I think that area is more interested in fairly loud dining and bar places.
