Back in 2008, while I was en route to my new home in South Korea, I made up my mind that I would avoid criticizing, at least in a negative way, whatever I observed in South Korea, and would simply live and learn. Well, one thing I think I've learned is that either Koreans LOVE sauce or so many cooks in so many restaurants LOVE using sauce. YES, they are flavored.
Take a look at the hotdog in the picture above. What I ordered was a chili dog, but what I had in mind was a hot dog topped with chili with beans as I was accustomed to in the USA. This is what I got. The red sauce is the chili (sauce). Well, I paid only 2000 wons (less than $2) for it.
