There is a place near Alphabet City in New York City, where there are a number of Indian Restaurants packed into a block, next to each other and vary externally with different color stands of tinsel. That's it as far as I can tell. Where do you start? You would have to try them all to determine the differences. The onus was on the restaurant to somehow prove it's higher quality or lower price. I guess if you live there you have the time to do this. I did not. I can't remember what restaurant we chose.
