After implementation of "Best Burger" concept, the recipe of buns in McDonald's changed. Burgers look better now and some changes, such as bigger amount of sauce for example, are fine. But we don't like the new bun. It's dry and feels like regular burger from any fast food.  Eating "Big mac", we don't enjoy it anymore. The unique experience and charm we had before - is gone. We want the previous bun back!!!!!!
