I don't think they're missing out - they probably enjoy a good Indian restaurant as much as we do. But for what they measure, that's tilted toward a certain kind of presentation that is predominantly done by French and Japanese restaurants. It's not just about the food, and how enjoyable the food is. It's about the wine selection, the interior decoration, and a whole host of other things.
Rather than resenting the Michelin system for not representing the kind of restaurants we love, maybe just recognize that it's not supposed to do that, and find other ways to find and measure restaurants that don't fit the Michelin data model?
