How close is La Avenue Seongsu to Seongsu Station?
La Avenue Seongsu (라에비뉴 성수) is a dessert café about a 2-minute walk from Exit 2 of Seongsu Station. I finally got out to Seongsu after a long while, and this was the place I visited. It really is that close!

Seongsu has so many tangled alleys that finding your way can be a pain, but La Avenue Seongsu is so easy to reach from the station that it would make a great meeting spot too. A stylish vibe radiates from the entrance, so I was already in a good mood before going in.

How varied is the bread at La Avenue Seongsu?
Even among Seongsu dessert cafés, La Avenue Seongsu is famous for its wide, solid selection, so I had wanted to visit for a while. I'd heard it was packed with delicious things, from bread to cakes, so my expectations were high. And sure enough, the dazzling lineup that catches your eye the moment you walk in made it clear why people call it a holy land for bread lovers.


First off, the variety of bread is just enormous. From tiny, adorable breads to crisp-looking cookies, the range to choose from was so wide I got decision paralysis. The toasty smell of the bread filled the whole shop, so I was happily torn the entire time I picked. There are plenty of breads that work as a meal too, so any time of day seems like a good time to visit.


How much are the slice cakes at La Avenue Seongsu?
Most slice cakes at La Avenue Seongsu were in the ₩8,000 to ₩9,000 range. Above all, there were so many kinds of cake that choosing was half the fun. As a true Seongsu cake hotspot, you can feel the care that went into every single slice.


Prices were mostly ₩8,000–₩9,000, and given the size of the slices and the toppings, I found that perfectly reasonable. The strawberry cake seems to be famous for how pretty it looks, and the menu seems to rotate with seasonal fresh fruit, so it would probably feel new every time you come.

Are there drinks other than coffee at La Avenue Seongsu?
La Avenue Seongsu has a good range of teas and non-coffee drinks besides coffee. The coffee menu was laid out like this, and I ordered an iced café latte, which goes best with sweet desserts. The menu was neatly organized and easy to read. People who don't drink coffee have plenty of options, which is nice.


What are the seats like for a solo café trip in Seongsu?
La Avenue Seongsu had lots of seats that are great for being alone. After ordering, I took a slow look around the interior. Many trendy Seongsu spots have uncomfortable seats or tables crammed together, but here the layout is relaxed, and there were plenty of spots where you can work on a laptop or read a book without feeling self-conscious.

Overall, the stylish interior really stood out. It seems a lot of thought went into every light, and the furniture and props are very trendy, so it's a lovely place for photos. A sleek urban feel and a warm mood coexist, so I felt at ease the whole time. The interior lifts the café's class a notch, and it would be a perfectly good date spot too.

Floor-to-ceiling window seats and the terrace
I wanted to watch the view outside, so I sat in a seat facing the window at La Avenue Seongsu, and it was quite nice. Through the big windows I could watch people go by and soak up Seongsu's lively street atmosphere, so my 2 hours alone at the café were never boring. There's also a terrace right next to it. It might be a bit chilly right now, but on a nice day I couldn't help thinking I'd love to sit out there soaking up the sun.

After you order at the counter at La Avenue Seongsu, they hand you a vibrating buzzer, and even the wait for it to go off was exciting.

How do the chestnut cake, financier and strawberry jam cake taste at La Avenue Seongsu?
At La Avenue Seongsu I ordered three things: chestnut cake, a financier (a small French almond butter cake) and strawberry jam cake. I wanted to really experience the charm of Seongsu desserts, so I got a little greedy, and it turned out to be an excellent choice. They were plated so beautifully that I couldn't help snapping photos for ages. Maybe because each one is made with such care, just looking at them raised my happiness level.


With the first sip of the café latte, the nutty richness of the milk spread through my mouth and blended really well with the flavor of the beans.
My top pick: the chestnut cake
The item I'd recommend at La Avenue Seongsu is the chestnut cake. It showed the very essence of a true Seongsu cake hotspot. The subtle sweetness of chestnut and the soft cream went together wonderfully, and there were chestnut pieces to chew on inside, so the texture was great too. The sweetness wasn't artificial; it brought out the natural flavor of the ingredients, so I enjoyed it to the very last bite. The financier was the textbook crisp-outside, moist-inside, and the strawberry jam cake added a fresh tang that made it a real treat.
Is La Avenue Seongsu worth going back to?
La Avenue Seongsu, a Seongsu cake hotspot, has it all: easy access, great flavor and atmosphere, so I think I'll be visiting often. I'll especially keep thinking about the nutty, sweet taste of that chestnut cake. If you're planning a day out in Seongsu, I recommend stopping by La Avenue Seongsu for a sweet break. For anyone who loves bread and cake, I'm sure it will feel like heaven.
