[1][2] He is currently the senior restaurant critic for New York magazine, a position he has held since July 2000, when he succeeded Gael Greene.

Before becoming a full-time restaurant critic,[7] Platt wrote and worked for many publications including The New Yorker,[8] where he was a Talk of the Town staff writer, The New York Observer and Elle, where he wrote monthly columns, and Condé Nast Traveler where he was a contributing editor for many years and travelled on assignment to the Southern Island of New Zealand, Botswana, China and Tokyo.

[9] He also spent time working and living in Washington, D.C. and is the co-author of columnist Joseph Alsop's memoir, I've Seen the Best of It.

[13] In the early Aughts Platt coined the term "Haute Barnyard" to describe the Farm to Table craze sweeping the gourmet restaurants of New York City.

[17] In January 2014 he became one of the first prominent restaurant critics in the US to do away with what he described as the pretentious "Kabuki dance" of fake disguises and anonymity, when New York magazine's former editor, Adam Moss, decided to feature him on the cover.
