It's always promising when you walk into a restaurant that features a menu with less than 10 items and still have people constantly waiting for tables.
As the restaurant name suggests - try the soon tofu chigae here and you'll be hooked. I think what sets this place apart is the richness of the broth, you can really taste the difference. They have a variety of choices for their tofu stew (kimchi, beef, seafood, combination, dumpling etc.) I've tried them all and each of them have been equally amazing. They also serve bibimbap and bulgoki here but please give the tofu chigae a try!
