Walk through Seongsu or Hongdae on a Saturday and you will see it. A line curling around the corner, everybody on their phone, all waiting for one bakery.

Koreans even have a word for the sprint before opening time: open-run (오픈런, opeun-reon). People show up before the doors do.

So the question every visitor ends up asking: is it actually worth it?

Why does everyone queue?

A long line is the cheapest advertising there is. Sixty people waiting means the place must be good. Right?

Then there is the photo. A cake you waited an hour for looks better on your feed. It even tastes better, funny enough.

And sometimes the shop really is great. That happens too. It is just less common than the line suggests.

What is in the line right now

Trends move fast here. One craze hands the baton to the next, and lately it is all chewy, crunchy, or both:

• 두쫀쿠 (dujjonku), the Dubai chewy cookie that started the run.
• 버터떡 (beoteo-tteok), the "Shanghai butter rice cake": chewy inside, crisp at the edges.
• 초코바게트 (choco baguette), a baguette with a deep, dark chocolate flavour.
• 양쯔깐루 (Yangzhi Ganlu), the Hong Kong style mango dessert with sago.

Notice something? Every one of them is easy to photograph and easy to queue for. I do not think that is an accident.

And the cycle is fast. Yakgwa, tanghulu, Dubai chocolate, 두쫀쿠 (dujjonku), now butter rice cake: Korean news keeps pointing out that a dessert craze can be over in a few months. Earlier this year, reports from Seongsu even mentioned weekend waits of several hours for the hottest ones. By the time you read this, the line may have moved on to something else.

Where the lines gather

Queues are not random. They pile up on a few streets, and once you know them you can plan around them.

• 연무장길 (Yeonmujang-gil) in Seongsu. The main street of the old warehouse district, lined with pop-up spaces, bakeries and brunch spots. Weekends are the busiest, and some pop-ups hand out queue tickets or want a reservation on the day.
• Hongdae (홍대). Cafés, snack stalls and dessert shops all around the station. Lines tend to be longest on weekends, afternoon into evening.

How long is too long?

Here is my rule of thumb. Not science, just a starting point. Yours may differ.

Bakery

Bakeries are the easiest to judge, because you can see the tray. When the good stuff sells out by early afternoon, the line is telling you to come earlier or not at all.

Dessert café

This is where lines fool people most, and the trendy ones above are the perfect example. You are often paying for the hype and the photo. The dessert is usually fine, rarely life-changing.

Forty-five minutes for a good cake is hard to defend. A bad one even harder.

Restaurant

Restaurants are different. A noodle shop with a lunch line of office workers is worth 20 or 30 minutes. The line usually moves faster than it looks, and the food is the whole point.

Queue smarter

• Go on a weekday, before opening or in the quiet hour around 3 pm.
• Use a waiting app. Many popular places let you join the line from your phone and come back when your turn is close. CatchTable Global is the one to try as a visitor: travel guides say you can sign up with Google, Apple or an email address. Tabling is mostly built for locals and usually wants a Korean phone number.
• Do not wander too far. If your name is called and you are not there, you can lose your spot, so keep an eye on the app.
• Look for a QR code at the shop front. Some places put one by the door: scan it, join the waiting list online, then wander off and come back when your turn is close. It is the easiest trick of all, and it saves you from standing there. If it asks for a Korean phone number, look for a "no Korean number" option before you walk away.
• Ask the staff how long it will take. They know, and they usually tell you straight.
• Keep a plan B two doors down. Korean streets are full of good places with no line at all.

Our verdict: about 20 minutes is the happy limit for food, and maybe 40 for a bakery you really want. Past that, the best part of your trip is spent standing still.
