What food should I try in the USA?

Hi, my dear fellow classmates and trainees! I'm Sunny(S03-07).
How was your life here at KNUE? As for me, it's a mixture of some stress and a little fun.
I heard many of you have been to the United States. I have never been there, so what kind of foods shoul I try when I get there? What was your most favortite food in America? Or what kind of extra activity will be helpful? Please give me some advice depending on your experience. Any tips will be appreciated! I hope you fully enjoy the rest of life here at KNUE. See you...
