Ttosuninae (또순이네) in my personal opinion has the best Korean Soybean Paste Stew (Doenjang-jjigae (된장찌개)) in all of Seoul, if not Korea.

If you go during lunchtime (11:30 ~ 14:30), you can enjoy this hearty, healthy stew beloved by all Koreans just for KRW 6,000 Won. (5.14 USD)

There is no break time, but if you go after 2:30 p.m, you have to order beef as well. The beef isn't bad either. They have 3 kinds of beef and the price is very reasonable.
(marinated hanging tender, marinated sirloin, and not-marinated sirloin).

However, their specialty is definitely the Soybean Paste Stew, so I recommend that you go during their lunchtime :)

It's about a 10-minute walk from Dangsan Station (Line 2 & Line 9). Google Maps doesn't work in Korea, so I recommend you use Naver Map or take a taxi. For those of you taking a cab, you can screen capture +03:09 and show your driver the address.

This is the first of a new series, where I will introduce some of the best restaurants that are also my personal favorites. Please subscribe and press like if you would like to see more of these content.
