Zagat still exists? Isn't it a bunch of old reviews written by a handful of writers?

Admittedly I haven't tried as their site runs off a "pay to see the full content of this review" model.
The Michelin Guide is actually a 'bunch of reviews written by a handful of writers', which isn't a bad thing in my opinion. Every restaurant I've been to that's even been Michelin rated has been superb.
Zagat has always used a crowd-sourced model, collecting customer reviews and publishing them in book form. They haven't really adapted this as well online (I'm sure this is where Google will give them a huge boost), but their approach was always UGC before people talked about UGC.
