Sign explaining the 5-level heat selection

What I loved most was the 5-level heat selection!! Level 1 is a mild, easygoing flavor, level 2 is slightly spicier than Shin Ramyun, level 3 and up starts to numb your mouth, and levels 4–5 are for the spice enthusiasts, they said. I visited with my mom, who can't handle spicy food well, so we ordered level 1, but next time I'd like to try level 2 with my husband haha. We ordered the small size boneless agujjim.

How does the level 1 boneless agujjim taste?

After a short wait, the boneless agujjim arrived, looking delicious with its red sauce! The small size was plenty for two, packed with plump boneless monkfish, roe/milt, and a generous amount of bean sprouts.

We ordered it at heat level 1, and while there was a slight spicy aroma at first, it wasn't harshly spicy — just the right amount of heat! The sauce had a clean, savory flavor that kept us reaching for more without getting tired of it.

A bite combining monkfish and bean sprouts

The monkfish meat was soft and plump, and eating it together with the crunchy bean sprouts gave it a really nice texture.

Dipping it lightly in soy-wasabi sauce added a sharp kick and a whole different flavor. Personally, the sauce was so tasty but not too intense, which made it great to share with my parents.

Why you should order the finishing fried rice at Sinseong Agujjim

Fried rice cooked with the leftover agujjim sauce

And you can't skip the fried rice! I was already full and debated it, but we ordered just one serving, and it was still a generous portion! They scoop out the agujjim sauce separately and fry it up nice and savory, so I enjoyed it all the way to the last bite.

You absolutely have to add the fried rice! It's so good you'd regret skipping it~
