If you’ve been watching Teach You a Lesson, you already know the moment. A GS25 convenience store, a character grabbing snacks like it’s the most natural thing in the world, and the rest of us immediately pausing to wonder: what is that, and where do I get it?
TikTok searches for the Teach You a Lesson GS25 eating scene spiked after the episode aired [VERIFY: episode number and exact timing], which tells you everything you need to know about how the drama has been landing internationally. This guide breaks down every Korean convenience store food featured in the drama, explains what each one actually is, and tells you how to get your hands on them — whether you’re planning a trip to Seoul or just shopping online from home.
The GS25 Scene That Had Everyone Searching
In Teach You a Lesson, the convenience store scene works because it’s so casually Korean [VERIFY: episode number for accuracy]. The characters don’t make a big deal out of stopping at GS25 — it’s just what people do. That blend of ordinary everyday life with the drama’s tension is exactly why fans noticed it. When a character eats something that looks genuinely delicious in the middle of an emotional scene, people want to know what it is.
The fact that GS25 is instantly recognizable to anyone who’s ever watched a Korean variety show or travel vlog made the moment land even harder internationally.
What Is GS25? (And Why Is It Always in Korean Dramas?)
GS25 is one of Korea’s largest convenience store chains, with over 16,000 locations across the country. Korean convenience stores like GS25 are known for genuinely good food.
We’re talking freshly made hot items, quality grab-and-go meals, and snacks you’d actually seek out rather than settle for. The hot food counter (with rotating corn dogs and fish cakes), the ramen station where you cook your own cup noodles at a little hot water machine, the wall of triangle kimbap in dozens of flavors — it’s a whole experience.
K-drama writers use GS25 as shorthand for an everyday, relatable moment. It’s where characters go when they need comfort food fast, when they’re stressed, when they’re having a late-night conversation that matters. It’s become almost its own dramatic setting.
Every Korean Convenience Store Food in Teach You a Lesson
Triangle Kimbap (삼각김밥)
The triangular rice ball is Korea’s most iconic convenience store food. Wrapped in seaweed with a thin layer of plastic between the seaweed and the rice (to keep it crispy until you open it), triangle kimbap comes stuffed with fillings like tuna mayo, bulgogi, spam, or kimchi. Opening one correctly is a three-step process involving pulling tabs in a specific order — and it’s become something of a rite of passage for first-time visitors to Korea.
Where to buy: Triangle kimbap isn’t available for international shipping since it’s a fresh product. Your best bet is a Korean grocery store near you, or — honestly — just go to Korea and try one fresh. If you want to make your own, look for seasoned rice and filling recipes online.
Cup Ramyun (컵라면)
There is something deeply satisfying about watching a Korean drama character eat ramen from a paper cup using chopsticks pulled from the dispenser next to the hot water machine. It’s a whole ritual.
The world of Korean cup ramyun runs deeper than most people expect. Flavors alone span spicy broth, mild broth, jajang (black bean), and seafood — across dozens of varieties — and the format splits into soup-based, stir-fried, and cold-mixed styles. Prices vary just as widely, from budget options under ₩1,000 to premium lines pushing ₩3,000 and up. The most commonly spotted brands in GS25 include Shin Ramyun and Samyang’s Buldak series, though specific products shown in Teach You a Lesson are pending verification.
Where to buy: Shin Ramyun and Buldak are widely available on Amazon, Weee!, and H Mart Online. They’re some of the easiest Korean snacks to find internationally.
Korean Corn Dogs (핫도그)
Not the corn dogs you grew up with. Korean convenience store corn dogs are coated in a thicker, sometimes rice-flour batter and often stuffed with mozzarella cheese, half sausage and half cheese, or rolled in a sweet potato coating. GS25’s rotating corn dog display under a heat lamp is genuinely iconic at this point in K-drama history.
Where to buy: Frozen Korean corn dog kits from brands like Dongwon or Bibigo are available on Weee! and at some H Mart locations.
Banana Milk (바나나맛 우유)
The chunky little bottle of Binggrae banana milk has appeared in more Korean dramas than we can count. It tastes exactly like banana candy in the best possible way, and it has a kind of nostalgic comfort to it that Korean audiences recognize immediately.
Where to buy: Available at most H Mart locations and on Weee!. Also worth checking your local Asian grocery store.
