I wasn't born and raised in Seoul. I grew up in Namhae, a small rural town on Korea's southern coast, and moved to Seoul at 19 to attend university after graduating from high school. When I first arrived, I wasn't much different from any other international visitor. I visited the famous attractions, searched for popular restaurants, and spent my time taking photos.
Everything changed once Seoul became the place where I actually lived. As I settled into everyday life, I began noticing habits and unspoken rules that I had never experienced growing up in the countryside. To most Seoul residents, these behaviors are so ordinary that they rarely think about them. For me, however, they often sparked the same thought: "Why does everyone do that?"
Whether it was choosing a seat on the subway, sharing a meal at a restaurant, or simply stopping by a convenience store, I kept discovering small details that only became visible through daily life. Not all of them are unique to Seoul—many, such as Korean dining etiquette, reflect the country's culture as a whole. Whether you're planning your first trip to Seoul or have just started living here, I hope this guide helps you understand the little everyday customs that often make you think, "So that's why people do it."

1. The Unwritten Rules of the Seoul Subway
Why Do People Prefer the Corner Seats?
One of the first things you'll notice on the Seoul subway is that, even when several seats are available, passengers almost always choose the ones at either end first. I'm exactly the same. With a wall or window on one side, those seats offer a little more privacy and are perfect for leaning your head against the glass during a long ride. On busy commuter lines, even a small amount of extra room feels surprisingly valuable.
Avoid Rush Hour
Visitors will have a much more comfortable experience by avoiding rush hour whenever possible. Flexible working schedules have become more common in recent years, with many offices allowing employees to start between 8 a.m. and 11 a.m. Even so, trains are still packed from 8 to 9 a.m. and again between 6 and 8 p.m.
Personal Space in a Crowded City
Despite South Korea's high population density, people on the subway naturally avoid making eye contact and try not to disturb those around them. Loud phone calls and conversations are uncommon. Sharing crowded trains every day seems to have created an unwritten rule: respect other people's space.
When the train is packed so tightly that there's barely room to breathe, the carriage often becomes even quieter. Everyone seems focused on simply getting through the journey. I was genuinely surprised the first time strangers started chatting with me on the New York subway. In Seoul, that almost never happens.
Let People Get Off First
As the doors open, passengers waiting on the platform usually step to either side and allow everyone to get off before boarding. You'll hear the same message in station announcements, and most people naturally follow it. Of course, there are always a few people who rush in before others have stepped off, so don't be surprised. Every city has people like that.
Waiting on the Platform
Passengers who aren't transferring can line up almost anywhere. Those changing lines, however, should check the platform signs first. They indicate which subway car is closest to the transfer exit, making the connection much easier. You'll also notice that people usually wait in two orderly lines before boarding.
Traveling with a large suitcase and no available seat? Head to the first or last car of the train. These cars often provide a little more room for luggage, and you can comfortably lean against your suitcase while standing.
I've also heard that some visitors misunderstand it when the Korean passenger next to them moves to another empty seat, assuming it's because of their race. In reality, that's rarely the case. As soon as another seat opens up, many Koreans simply move to wherever they have a little more space. It's a matter of comfort, not discrimination.
2. Korean Dining Culture at the Table
Putting Your Phone Face Down
In many Korean restaurants, you'll notice people placing their smartphones face down on the table instead of keeping the screen visible. It's a small gesture, but it's often seen as a sign of respect for the person you're sharing a meal with. Constantly checking your phone while someone is sitting across from you can easily make them feel ignored.
Of course, not every Korean follows this habit, but many people see it as a way of saying, "I'm here with you, and you have my attention." Making eye contact and staying engaged in the conversation generally leaves a better impression than repeatedly looking at a phone. It may seem like a small detail, but to me, it's one of the everyday ways people show consideration for one another.
Sharing the Grill at Korean BBQ
Eating Korean barbecue is very different from ordering individual plates. Instead of everyone cooking their own portion, the meat is placed on the grill in the middle of the table and shared as it finishes cooking. Before long, someone naturally becomes the unofficial "grill master" because they're simply better at cooking the meat.
These days, many Korean BBQ restaurants have staff who cook everything for you. If it's your first time trying Korean barbecue, I'd recommend one of those places so you can simply relax and enjoy the meal. These days, I actually prefer restaurants where the staff grills the meat for you too.
Tipping is not expected in Korea, and at most restaurants you don't need to leave one. Some high-end restaurants may accept tips for exceptional service, but it's entirely optional.
Why Do Koreans Share Side Dishes and Stew?
Many Koreans grew up sharing a pot of stew with family members, each taking spoonfuls from the same dish. Side dishes are also placed in the center of the table for everyone to enjoy rather than being served as individual portions.
If you come from a culture where personal plates are the norm, this may feel unfamiliar at first. Fortunately, many restaurants now provide small side plates on request, and using serving utensils or taking your own portion first has become increasingly common in Korea.
My Food vs. Our Food
At the heart of Korean dining culture is the idea that the meal belongs to everyone at the table rather than to one person. It's common to order a pasta, a pizza, or several different dishes and share them together instead of keeping each plate to yourself.
For me, that's one of the best parts of eating in Korea. Instead of ordering separate meals, everyone gets to try a little of everything. It's less about "my food" and more about enjoying the meal together.
3. Why Korean Convenience Stores Are More Than Just Stores
More Than a Place to Buy Snacks
Korean convenience stores are everywhere—sometimes it feels like there's one on every corner. One thing many visitors find surprising is that many locations have tables and chairs inside or just outside the store, making it easy to sit down and eat right away.
Traveling can be expensive, especially after shopping or stopping by cafés throughout the day. Convenience stores offer an affordable alternative, with everything from lunch boxes to instant noodles that can be prepared on the spot. Some larger branches even have spacious seating areas that feel almost like a highway rest stop. If you're planning to grab a quick meal, it's worth checking whether the store has a dining area before you go.
One of the Most Useful Places While Traveling
Convenience stores sell far more than snacks, drinks, bread, and ready-to-eat meals. They're also a great place to pick up everyday essentials such as over-the-counter medicine, toiletries, or other items you might suddenly need late at night. Whether you're looking for a toothbrush, toothpaste, or facial cleanser, there's a good chance you'll find it nearby.
If you get hungry at an odd hour or realize you've forgotten something during your trip, there's no need to panic—just head to the nearest convenience store. Some business hotels in Seoul even have one located inside the building, making them even more convenient for travelers.
4. "I'm Fine" Doesn't Always Mean "I'm Fine"
More Than Just "I'm Fine"
One Korean expression that still confuses me in everyday life is "Gwaenchanayo" (괜찮아요). Sometimes it genuinely means "I'm fine" or "It's okay." But just as often, people use it when they feel uncomfortable or want to politely decline something. There have been plenty of moments when I've caught myself wondering, "What exactly does 'it's okay' mean this time?" Honestly, I still wish people would just say exactly what they mean.
Reading Between the Lines
For example, when you offer someone something and they reply, "Gwaenchanayo," it may truly mean they don't need it. On the other hand, it can also be a polite refusal before accepting, simply out of courtesy. People may even say it in situations where they're actually feeling uncomfortable, so understanding the real meaning often depends on their facial expression, tone of voice, and the situation itself.
I think this way of speaking comes from a desire to keep conversations smooth and avoid making others feel uncomfortable. Rather than saying "No" or "I don't want to," many Koreans prefer softer, more indirect expressions. So if someone says "Gwaenchanayo" to you, asking one more time, "Are you sure?" is often perfectly acceptable.
5. The "Ppalli Ppalli" Culture and Seoul's Lunch Hour
Why Everything Moves So Fast
The speed of restaurant service, food delivery, and even internet connections—what I feel most strongly while living in Seoul is just how fast everything moves. Outside Seoul, I don't think the ppalli ppalli culture feels quite as intense. Life was much more relaxed when I lived in the countryside. Order a coffee at a café, and it usually arrives within a few minutes. Food delivery often reaches your door around 30 minutes after you place the order through an app.
Once you become accustomed to that pace, slower service elsewhere can actually start to feel frustrating.
Lunch Hour Says It All
Lunch is when this culture becomes most obvious. Seoul office workers usually have exactly one hour, from noon to 1 p.m. The problem is that they have to walk to the restaurant, wait in line, order, eat, pay, and return to the office within that time.
These days, many restaurants are already full by noon, and office workers often start heading out around 11:30 a.m. to secure a table. It shows just how competitive lunchtime can be.
For people who have to finish their meal and get back to work within such a short break, moving quickly is almost inevitable. Try to avoid lunchtime in business districts such as Yeouido, Gangnam, and Samseong whenever possible.
