Excerpt from this article:
When reviewers picture authenticity in ethnic food, they mentally reference all the experiences they’ve had before with that cuisine and the people who make it — and most of the time, reviewers view those experiences, whether from personal interaction or from interacting with media, as not positive. Reviews tend to reflect the racism already existing in the world; people’s biases come into play.
According to my data, the average Yelp reviewer connotes “authentic” with characteristics such as dirt floors, plastic stools, and other patrons who are non-white when reviewing non-European restaurants. This happens approximately 85 percent of the time. But when talking about cuisines from Europe, the word “authentic” instead gets associated with more positive characteristics. This quote from a reviewer commenting on popular Korean barbecue restaurant Jongro illustrates the bias: “we went for this authentic spot with its kitschy hut decor much like those found in Korea”
