Yupdduk
I have eaten at my fair share of Korean restaurants (I lived in Seoul for two years), and to be honest, I never found the food to be that spicy. Delicious, to be sure, just not super hot. But Yuppduk’s “EXTREMELY SPICY” rice cakes, called topokki (or ttoekbokki or teokbokki or ddeokbokki—the English spelling options are endless!), deserve a place at the bottom of this list. If you have never tried topokki, they’re extremely chewy little pasta-like logs (or slices) made out of pounded rice. They come served up in a sweet, red spicy sauce, often with some fish cake and cabbage, and are one of Korea’s most popular street foods. These had a nice kick, which had my nose running and my lips tingling. If you’re a spice-addict roaming around K-town, these are good bet.
