This week’s mystery closing: NIGHT AND DAY at 230 Fifth Avenue. An OTBKB reader said the store looked boarded up. I was disbelieving. How is it possible, I said. Two professional restaurant owners: He from Cornelia Street Cafe, she from the Lion’s Head. Sure, there were ups and downs until they got that great chef from New Orleans last year. But hasn’t the back room been a much needed cultural space in the nabe? So what gives? I am utterly SHOCKED that they didn’t give it more than one year and a little more. I think the owners owned the building so maybe they just decided: who needs the bother of running a restaurant, be landlords instead. Maybe Robin Hirsh will still run the backroom. Do I know what I am talking about. Nah.

But I do know this: a reader wrote to say the Biscuit (formerly of Flatbush Avenue) is going in. One door closes another door OPENS. It seems that people have lots of OPINIONS about the old biscuit. Check out the Daily Heights message board to hear it all.

The new BISCUIT is “opening soon” at 230 5th Avenue.
