Yes, I tend to google and download wikitravel when I travel - this was back in 2011 when we went to Taipei, and keep a copy plus map of vegetarian places, although my husband is not vegetarian. In the end, I found a few snack options at the night markets, and survived. so far, never been sick from market food. In Seoul, I just go to the markets and eat the leek pancakes and pickles, or head to a monastery for lunch.
