It was an afternoon with a slightly refreshing breeze, and I wasn't in the mood for just any coffee to caffeinate — I wanted really good coffee. After visiting Children's Grand Park, I finally made it to Wonz Coffee's Guui branch, which had been buzzing with a reputation for great coffee nearby.

This was a place where you could enjoy properly flavorful coffee and a cozy vibe at the same time. I'd recommend it if you want to rest after a walk in nearby Children's Grand Park, or if you're looking for a Guui Station café.


Wonz Coffee Children's Grand Park Main Branch: a Gwangjin café with four beans to choose from
This place has a lineup of four beans — Black Blend, Red Blend, Green Blend, and Yellow Blend — so you can choose coffee that fits your own character and taste.
I visited around 1:30pm and the café was already about 90% full of customers, so I could immediately feel how popular it was. With great-tasting coffee plus free refills, it seemed like a lot of people were drawn in.


Inside Wonz Coffee: window light and cozy, stylish décor
Stepping inside, a huge window pouring in light caught my eye right away. Sitting by the window, the warm sunlight wrapped around me and warmed up my body, which had gone cold from the air conditioning.
The interior overall is a clean mix of white and black, and green plants placed here and there along with stylish accent frames and props come together harmoniously to create a space that feels both comfortable and emotive.





What we ordered at Wonz Coffee: decaf coffee, milk bingsu and egg tart
You order through a kiosk. I wanted to fully experience this place's deep, honest coffee flavor, so I picked an americano, and paired it with a milk bingsu (shaved ice dessert) to cool down from the heat of walking over.
In front of the bakery corner, I fell into serious deliberation (?) between the sweet, nutty kaya toast and the crispy-outside-tender-inside egg tart, and ended up going with the egg tart to finish my order.
- Decaf coffee 4,900 won
- Milk bingsu 12,000 won
- Egg tart 3,500 won


Milk bingsu, 12,000 won: dense snowflake ice with a nutty, milky sweetness
Here, you enter your table number on the kiosk when ordering, and staff bring the food out — I got everything I ordered served together on one tray, generously.
The milk bingsu's mounded look caught my eye right away. Looking at it, it seemed light and fluffy like falling snowflakes, but when I scooped up a big spoonful, I found a texture that was quite dense and rich.


The moment it hit my mouth it melted right away, spreading a rich, nutty milk flavor throughout, with a subtly sweet finish that never got tiring.
Instead of an artificially strong sweetness, the nutty flavor took center stage, making it a bingsu dessert that was clean and refreshing to enjoy.




Decaf americano, 4,900 won: pour the shot over ice yourself
I understood immediately, from the very first sip, why this café's coffee had gotten so much praise. It's genuinely hard to find delicious decaf coffee, but here, the aroma and overall balance were great.
On the first sip, I got a rich, sweet-and-bittersweet dark chocolate-like aroma, and after swallowing, a nutty pecan-like aftertaste lingered pleasantly in my mouth for a long time — really charming.


True to a place that values the customer's experience, Wonz Coffee serves the coffee shot separately in a small container, so I got the small pleasure of pouring it into the ice-filled glass myself. Being able to adjust the amount of shot to find the exact strength I liked made it even more satisfying.
Egg tart, 3,500 won: crackling pastry with soft cream inside
The egg tart I tried last was truly something else. This café's egg tart has an unusually crackly, crisp pastry shell texture.
Behind the crispness of the thin, layered pastry, the egg custard filling inside was so soft it jiggled and wobbled.
With one bite, the outside crackled while the inside melted away softly like pudding, and the rich, sweet flavor of the egg custard wrapped around my whole mouth.
