Just as a general opinion, restaurant reviews or recommendations are always extremely subjective and usually overrated. TripAdvisor is notorious for false reviews. Any restaurant can change quickly with a new chef, financial strains (small portions) or just the viewpoint of the individual reviewer. People's tastes are so different on what is very good or what is meh.
I believe most restaurants in Europe are reviewed higher by Americans than locals because of the lack of experience in the local or regional cuisines. This is why it is great if a hotel or other local source will offer up a favorite of their own.
When RS goes to a restaurant he is treated like the travel celebrity he is because his review or recommendation means a lot to a restaurant owner. The restaurant puts its best foot forward for him. Other patrons will usually not get the same service or special touch awarded to a person like RS normally. There are exceptions, but few and far between.
