We've always preferred Katz's, but the threat of famed Carnegie Deli closing still has us a little verklempt. The deli has had a longstanding arrangement with nextdoor neighbors Woodward Affiliates, who allow Carnegie to use some of its property for extra seating and a required second emergency exit for $2,500 a month. But as the two sides were working out a new deal with the Buildings Department last week, Woodward allegedly bailed and Carnegie filed a suit. The suit claims, "The failure to obtain a public assembly permit may, and likely will, result in the closure of the Carnegie Deli."
