It looks like an event called the Busan Pork Soup Battle is being held.

I went out to eat with my family yesterday evening and saw something like this, so I checked it out. I think I've been to about half of the selected places, and I found it interesting that Sikbok Pork Soup, which I went to yesterday, was linked even though it hasn't been open for very long.

The taste was just like any other newly opened soup restaurant, so I wonder how it was selected? Out of the 20 establishments, I'd say Yongho Hapcheon is 1st, Subyeon Choegoga is 2nd, and Sinpyeong Yeongjin is about 3rd.
By the way, about 8 out of the 20 places are near my neighborhood. Wow.
