The old reviews are still there (for now) but new ones are not being written. I believe the employees involved are no longer employed by he NYT.
The JN doesn’t even claim to have reviews, so maybe they’re better than WM in that regard (although shouldn’t one expect a major local newspaper to critically review restaurants?). I had complained to Liz Johnson about this a while ago but to no avail. Their current food editor left recently, and the job description that Liz posted looking for the replacement specifically said that reviews were not a part of the position.
