“Michelin Red Guides have become widely known as the world’s most respected source of restaurant and hotel evaluations, with the famed Michelin stars serving as an international symbol of culinary excellence.” - Source 
But from a vegetarian or especially vegan point of view the problem is that the Michelin Guides are nearly "totally meat obsessed".
For example check the Michelin Guides for Europe or Asia.

Great Britain & Ireland - 1700 selected restaurants includes  only 3 vegetarian restaurants.
Italy - 2300 selected restaurants includes only 1! vegetarian restaurant.
A little bit better is the situation with the three Michelin Guides for North America.
