Business Insider had a few of its millennial coworkers try Shake Shack burgers. Some of them weren?t pleased by the way the burger looked but said they liked the taste. One person said they really like the bun, pointing out that it doesn?t take over the taste. Some said it taste even better than a McDonald?s or Burger King burger. Yet one person did say she liked McDonald?s better because of their thinner patty.
