Anguk burger spot: Chili's cheese sticks and Jack Morning at Jackjack

In short

Jackjack Anguk is a handmade burger restaurant on Yulgok-ro near Anguk Station in Jongno, Seoul, run by a chef who appeared on Culinary Class Wars. Joining the trend a little late, the writer ordered 2 Chili's cheese sticks (fried whole mozzarella) and the Jack Morning burger with a fried egg and hash brown; the cheese sticks stood out for their endlessly stretchy cheese and crisp coating, and the Jack Morning for its hearty build. Jackjack's Chili's cheese sticks have real presence, and even one is filling on its own.

What is Jackjack Anguk like?

Jackjack Anguk is a handmade burger spot in Jongno run by the chef (Jjaekjjaegi) who appeared on Culinary Class Wars, on Yulgok-ro near Anguk Station. I'd been once before. I ignored the Chili's cheese stick craze when it was hot, then saw one mukbang video and suddenly had to try it, so I went back to hop on the trend late.

Jackjack took over Itaewon and Gangnam, and now it has landed in Anguk too. They say they prepare oversized chicken and special sides so you can taste real American flavor. Making the best food matters, but apparently they also try to pass on positive energy, haha.

What are the seats and atmosphere like at Jackjack Anguk?

The 1st floor has bar seats, so eating alone is no problem. The bird-brain (?) mascot still greets you at this Jongno favorite, haha. The open kitchen you can see from the stairs up to the 2nd floor is impressive for an Anguk handmade burger shop.

Burger menu board at Jackjack Anguk

How has the Jackjack menu changed?

The menu seems to have been slimmed down. It looks focused on three chicken burgers and three beef burgers! I think the chicken patty used to be breast meat, and now it seems to be all whole thigh...?

There are some new items: besides the fried whole mozzarella, there are now Jack's Special Fries and buffalo wings. I think the fried mozzarella was limited to one per person at first, but now there's no limit. I also saw chicken rice bowls, and wraps are new too. Jackjack's latest news is on Instagram, so keep an eye on it!!!

The 2nd floor has roomy seating, so you can eat more comfortably. Is there a military base nearby...? Both before and now, I always see people in uniform here.

Self-service corner at Jackjack Anguk

What's at the self-service corner?

The self-service corner had disposable spoons and forks, wet wipes and napkins, plus free samples of things like jalapeños. I was curious and grabbed about three, lol. You always need wet wipes with a burger, so just take them early.

What did I order at Jackjack Anguk?

  • Fried whole mozzarella (Chili's-style cheese sticks), 2 pieces
  • Jack Morning
Table with the Chili's cheese sticks and Jack Morning order

Today's mission: the Chili's cheese sticks and the Jack Morning. Last time I had the signature Jackjack burger, but this time I picked the Jack Morning, an unusual one with a fried egg, named like a (very heavy) breakfast.

These pickled peppers were fresh and sweet, great when things get greasy. Tasty.

How do the Jackjack Chili's cheese sticks taste?

I ordered 2 cheese sticks. The trend may be over, but looking at other tables, everyone seemed to order one, lol. The incredibly stretchy cheese was just like in the videos.

Wow, it really does stretch...? Crazy, lol. The cheese is seriously thick, and this alone would probably fill you up.

How far does it go, hahahaha. The flavor is just a big cheese stick, but since it's freshly made the cheese hasn't hardened, so it was delicious, and it didn't taste like cheap cheese. The crunchy coating made it even better. The crispy outside and whole mozzarella seem to be the identity of the Chili's cheese stick.

It felt like playing with a toy made of cheese stick, which was fun. Kids would love it. The outside is red, but I didn't find it spicy at all. Even if it were, I think it'd be good! A spicy Chili's cheese stick challenge, haha.

What is the Jackjack Jack Morning burger?

Jack Morning is Jackjack's chicken burger with whole-thigh Nashville chicken, a fried egg, hash brown, maple syrup and cheddar cheese. Here it is, Jack Morning, wrapped up nicely.

Jack Morning normally comes with mayonnaise too, but I hate mayo, so I asked them to leave it out. It came out with mayo by mistake at first, and I thought about just eating it, but there was too much, so I told them. They could simply have remade it, yet they apologized several times, which I appreciated.

A golden toasted bun, and a hash brown too! It felt like a super lavish McMorning...? No real comparison, haha. Jack Morning packs in a huge amount of protein and calories ><
