I'm going to start by saying that those who complaint about the amount of political debates in the show, most probably is because they don't agree with Chang's position. But I do... Food is by far, the greatest way to represent a culture, and how much we value some food reflects perfectly how we value the culture behind it. And maybe it's about time that people in the states understand that all this food they like and often consider as their own, comes from cultures such as mexican, chinese, and black people, that deserves to be respected as well.
I'm a huge fan of Chang since Mind of a Chef, he is very honest and is not afraid of having uncomfortable conversations, and racism in the food industry is one of those.
That being said, the show is great: casual conversations among friends and experts, lots of delicious food, and a beautiful effort of showing that the greatest food of all is not in the expensive, elitist restaurants, but the one you share with your loved ones and is cooked with intention and feeling.
