Main photo from a visit to Jeongjeong-a Sikdang Jeongwang Branch

After stopping by the library a while ago, I went for a hearty lunch with friends at Jeongjeong-a Sikdang (정정아식당), a well-known restaurant in Jeongwang-dong. It's an old local rice joint, and the deeply flavored chicken stew made it a perfect lunch. I wondered why I hadn't come sooner. Besides the chicken stew, I also tried the life-changing seasoned cockles, so here's my honest review.

Parking in the Jeongwang-dong alleys is a pain, so not having to worry about it was great.

Domestic fresh chicken, Yeojaman Bay cockles

The signature dishes are said to be the premium chicken stew made with 100% domestic fresh chicken, and fresh cockles delivered straight every morning from Yeojaman Bay, then cleaned and prepped in the restaurant.

What we ordered for lunch after the library

😋 We went with the great-value Set 1 (cockles + acorn jelly), a small chicken stew (serves 2) at "not spicy (level 1)", and added extra rice for a generous spread.

By the way, the chicken stew here can be adjusted from not spicy to level 2 (Shin Ramyun-level) and level 3 (very spicy), so I think both spice lovers and people who can't handle spicy food can enjoy it.

Side dishes: water kimchi and napa cabbage kimchi

🥢 Honest dish-by-dish review

Seasoned cockles, the first dish served at Jeongjeong-a Sikdang

💯 Seasoned cockles that beat the ones I had in Beolgyo

The seasoned cockles (kkomak-muchim) were served first, and they looked overwhelming from the start. Maybe because they're domestic cockles sent straight from the source every morning, they were really plump, and every bite carried the fresh flavor of the sea.

Yeojaman Bay cockles tossed in soy sauce seasoning

The secret soy sauce-based seasoning wasn't too salty, and its sweet-and-savory depth was a work of art. The moment I took a bite I said, "Wow, this is really good!" They felt much fresher than the cockles I once ate in Beolgyo itself, and the seasoning had soaked right in. It had that deep flavor reminiscent of my mother's loving home cooking when I was little, so I'd absolutely recommend it, either on its own or as a side with drinks!

💯 Seriously bouncy acorn jelly salad

The acorn jelly salad (dotori-muk-muchim) in Set 1 came tossed with plenty of fragrant, nutty seaweed flakes and crunchy fresh vegetables. The jelly itself didn't break apart and was so springy that you could feel its elasticity even when picking it up with chopsticks.

It had a great chew in the mouth, and the tangy-sweet, appetite-boosting seasoning went perfectly with the vegetables, making it an ideal appetizer before the chicken stew.

💯 Tender chicken stew with a fantastic broth

Chicken stew with green onions and potatoes boiling on the burner

The chicken stew (dakbokkeumtang), the main dish here, quickly comes to a bubbling boil on the burner. The pot is packed with fresh green onions and onions, with plenty of fluffy, well-cooked potatoes layered on the bottom, so the generosity is surprising. Perhaps because they carefully select only 100% domestic fresh chicken, there wasn't the slightest gamey chicken smell.

Broth of the not-spicy chicken stew

I tried the broth first, and its deep, rich savoriness clinging to the mouth was superb.

The seasoning had soaked all the way into the chicken, and the meat was so tender and soft that bone and flesh separated easily.

Potato too

I mashed the fluffy potato and mixed it into my rice with the rich broth, and it was truly a "rice thief" (a dish that makes you eat lots of rice), so I couldn't stop gobbling it up.

As we ate, the broth reduced a bit, and a kind staff member noticed first and refilled the stock for us. That attentive service was touching. I want to eat it again!

Verdict: Jeongjeong-a Sikdang Jeongwang Branch, 100% would return

Hidden in a Jeongwang-dong alley, Jeongjeong-a Sikdang Jeongwang Branch was a perfect value-for-money spot with all three: the deep broth of the chicken stew, the freshness of the straight-from-the-source cockles and the bounciness of the acorn jelly!

Thanks to the friendly service and generous portions, I felt happy and full throughout the meal. Next time I want to come in the evening with coworkers, have some cool makgeolli (rice wine) or soju, and try the other set menus too. If you're looking for a proper Korean restaurant in Jeongwang-dong or a no-fail spot for a company dinner, go to Jeongjeong-a Sikdang without hesitation. Of course, I'm 100% coming back.
