It’s not a perfect replacement, but searching OpenStreetMap via https://overpass-turbo.eu/ with a query like

[out:json][timeout:25];
(
  nwr["diet:vegan"~"yes|only"]({{bbox}});
  nwr["cuisine"~"vegan"]({{bbox}});
);
out geom;

can be useful and is often more up-to-date with respect to restaurants that actually still exist.
