I'm not convinced that "study" says much of anything, since they almost certainly edited the video to show the responses they wanted, and besides, they didn't calibrate their scale properly. If you gave a bunch of random people at a food tasting event some pretty crappy food, a bunch of them would probably say that it tasted good just out of courtesy.

A better comparison would be to have a double-blind study with McDonalds and "Artisan" hamburgers, and ask participants which they prefer.
