I went to Seoul in May this year, it was okay. But the worst experience was that we ate at a barbecue restaurant, the meat was fine, but the the kimchi made us so sick taht we had to cancel our plan for the next day...I did some research and I found out that almost all the restaurants recycle the leftover kimchi that the customers didn't finish.... For people whose stomach is not so strong would definitely get hit. Just a reminder.
