Closest to you would be on the UWS (Neptune Room -- you can make a reservation).
I also like Pastis (brioche) or Jane (creme brulee battered). Those are in Meatpacking District and just north of Soho.
The Tasting Room (Nolita) has good french toast, too, but the focus is more on the seasonal fruit than the toast itself. I've also had it at Perilla, and it's quite tasty, and nontraditional, it's a brioche french toast with honey crisp apples. Not the best in the city but well done, and accompanied by a knockout raisin rum maple syrup compote.
All these places take reservations, BTW.
