A small bow or nod when you greet someone. Kids don’t need a full bow, a little head dip goes a long way, especially with anyone older.

Shoes come off indoors. Homes, guesthouses, some restaurants, anywhere with heated ondol floors. Look for the shoe rack by the door.

Age shapes how people speak to each other. You’ll hear it in restaurants and on the street. It isn’t rudeness, it’s respect built directly into the language.

Drinking has its own etiquette. Soju is the default, poured for others, never yourself, and you turn slightly away when you drink in front of someone older. You likely won’t be doing this with the kids underfoot, but it’s worth knowing.

Tipping is not expected, anywhere. Slide extra cash into a bill and you’ll usually just get it handed back to you.

Subways and buses are quiet and orderly. Priority seating is respected without question. Teach the kids to let people off before getting on.

Banchan comes with everything. A wall of little side dishes lands on the table before the main dish does, free, unlimited refills, which means there’s almost always something even a picky eater will touch.

Spice is more adjustable than people think. A lot of the famously fiery dishes have a mild version, or a kid can just eat around the sauce. Most places will work with you if you ask.

Korean BBQ is basically built for families. Everyone cooks their own, everyone picks what they want, and there’s always rice and lettuce wraps to fall back on if a kid isn’t feeling adventurous that night.

Street food is everywhere and cheap. Tteokbokki, hotteok, fish-shaped bread stuffed with red bean. Good way to let the kids try things in small bites without committing to a whole meal.

Convenience stores are a real meal category, not a last resort. Triangle kimbap, warm eggs, instant ramen you make right there. Some of our easiest family lunches in Korea have come out of a GS25 or CU.

KTX high-speed rail. Connects Seoul to Busan in under three hours and is the backbone of any multi-city Korea trip. Book ahead around holidays.

T-money card. Load it once, tap it on every subway, city bus, and most intercity buses, plus a huge share of convenience stores. Pick one up at any subway station or the airport.

Seoul and Busan subways are excellent. Clean, frequent, full English signage. Genuinely one of the least stressful metro systems we’ve used anywhere with kids.

Intercity buses fill in the gaps. Wherever the KTX doesn’t reach, a bus usually does, and Korea’s bus system is comfortable and reliable.

Use Naver Map or Kakao Map, not Google Maps. Google Maps’ directions are badly limited in Korea. Download one of the Korean apps before you land, it’s not optional.

The currency is the Korean won. Prices look enormous with all the zeros, budget a beat to do the math in your head for the first day or two.

Card works almost everywhere, except when it doesn’t. Big stores, chains, and the KTX all take cards without a thought. Small vendors, market stalls, and a lot of street carts are cash or card-machine-specific.

A Wowpass or T-money card solves most of it. Wowpass lets you load a foreign card and pull won straight from the kiosk, and it doubles as your transit card.

Get a SIM or eSIM before you land, or at the airport. Coverage is excellent everywhere, including underground on the subway.

Outlets are Type C/F, 220V. Bring an adapter. Most modern electronics handle the voltage fine, check yours before you go.

It’s about as safe as travel gets. I’ve let my kids walk ahead of me on a Seoul sidewalk in a way I wouldn’t at home, and it never once felt like a risk.

Extremely walkable, but plan for stairs. Subway stations can involve real staircases. A carrier beats a stroller in a lot of spots.

Jjimjilbang (spa) culture is family-friendly. Kids are welcome, and a proper Korean spa day is one of the best rainy-day plans you’ll find anywhere.

Kids’ menus aren’t really a thing. Pack snacks or plan to order a shareable dish. Most restaurants aren’t built around a kid-specific plate the way US restaurants are.

Playgrounds and kid cafes are everywhere. Even a random neighborhood in Seoul will have a play space tucked into it somewhere.

How safe it feels letting the kids range a little further than you would at home.

How good, and how cheap, the food is. A full family meal can run less than a fast food stop back home.

How much of daily life still runs on cash, even in a country this wired for technology.

How vertical everything is. Restaurants and shops stack up floors two through eight of a single building, with barely a sign at street level.

24-hour convenience stores are basically a public utility. Need a diaper, a phone charger, or dinner at 11pm, there’s a GS25 or CU within a block, always.
