It was a sad day a couple of years back when Sample chef and co-owner Josh Cohen closed Biscuit, his Park Slope barbecue restaurant. By now, you may have gotten over it. Which makes this an extra-special surprise: Biscuit is coming back. On Monday, Cohen finalized plans to convert Night and Day, at 230 Fifth Avenue (not to be confused with 230 Fifth Avenue, the Manhattan restaurant), into a bigger and better version of Biscuit, scheduled to open on October 30. His slow-smoked pork, spareribs, point-cut brisket, and chicken, along with other southern standards like fried chicken and u-peel-'em shrimp, will all be making a triumphant return. There will also be a full bar and blues and bluegrass music. "I think we have a chance to really do Biscuit right this time," Cohen told us. Hey, we liked it the last time.
