Grub Street has this from co-owner Chris Ronis
We've had a great run and are very proud of what we accomplished in this space in the last six years, but 2015 was a tough year and we did not manage to pull the nose up to restore the flight altitude we once enjoyed. We're hanging it up while we still have the buttons on our pants. The upshot we have about two weeks left before it's lights-out for Northern Spy, with our final service being Wednesday, February 17th.
Eater has more here.
If you want to stop by for a last meal, then don't do it this evening...
