Comfort Diner, Midtown, Manhattan
Update: I ate here a few weeks ago and they were open and the food was fabulous. They were however a little short staffed but well worth the wait. Long live NYC diners! Updated 13 July 2021
I've discovered a new favorite diner! They aren't new. But I don't know how long they've been around. The breakfast was fabulous. They were really nice and very efficient I might add. That is not always true of other diners. Also, I found that their quality and prices were really good. I will be returning there soon. It has a very traditional diner look as well!
