Do you count large-format meals?
If you want places that only take reservations for larger groups and you still order a la carte, I think that there's:
Blue Ribbon Brasserie & Blue Ribbon Bakery
Freeman Alley, New York, NY 10002
Blue Ribbon Brasserie
97 Sullivan St, New York, NY 10012
Blue Ribbon Bakery
33 Bedford St, New York, NY 10014
359 6th Ave, New York, NY 10011
Here's a large format feast list:
I would add on Wong (though I'm not sure how far in advance they book out now), Burger & Barrel, Maialino.
2 Lexington Avenue, New York, NY 10010
Burger & Barrel
25 W Houston St, New York, NY 10012
7 Cornelia St, New York, NY 10014
