I think everyone has a comfort food.  For many Koreans, I’m sure that if they were in a foreign place and wanted a specific food, it would be kimchi.  For me, it is apparently Coke.  I drank so much of it on my trip because it was usually the only familiar thing I could have.  Especially in Myanmar.  I am on pop detox now because I seriously drank at least one a day, which is gross and way more than I normally would.
