I spent three weekends hitting the trendiest cafes in Seoul so you don’t have to guess what’s actually worth ordering.
As a Korean dad living just outside Seoul in Gyeonggi-do, I don’t get into the city every weekend — work in the chemical industry keeps me busy, and my kid doesn’t exactly have the patience for long cafe queues. But this past May and early June, I made it a personal mission to track down five drinks that kept popping up on my Instagram feed, on Korean YouTube, and even on the office group chat. Some of them genuinely surprised me. A couple were, honestly, a little disappointing. Here’s my completely honest take on each one, with prices, exact spots, and tips so you don’t waste your time or your won.
Korean cafe: 1. Dalgona Espresso Tonic — Still Going Strong?
If you were paying any attention to Korean cafe culture back in 2020, you know dalgona. The whipped coffee foam thing. Well, in 2026 it’s evolved — cafes are now layering that same foam directly over espresso tonic, which is cold sparkling water with a shot of espresso. I tried this at Anthracite Coffee Roasters in Hapjeong, which has the industrial-chic vibe that makes every drink look cinematic.
The price was 7,500 won. The taste? Honestly really solid. The bitterness of the espresso cuts through the sweetness of the foam beautifully, and the tonic bubbles keep the whole thing lively. My one complaint is that you have to drink it fast — once the foam dissolves into the tonic, you lose that layered experience pretty quickly. For a first-timer, it’s a great starting point because it’s not too sweet and not too weird. Plenty of cafes around Hongdae and Insadong carry their own version now, so you have options.
2. Strawberry Basil Latte — The Instagram Queen of 2026
This one is everywhere. Seriously, I saw it on billboards near Gangnam Station, on cafe sandwich boards in Ikseon-dong, and my wife sent me a photo of it from her friend’s feed before I even went to try it. I finally got one at Cafe Onion in Anguk — a place already famous for its gorgeous hanok building setting — for 8,000 won.
The drink itself is a milk-based latte with a house-made strawberry compote at the bottom and a small sprig of fresh basil on top. When you mix it, there’s this unexpected herbal note that hits right after the sweetness. It sounds bizarre, but it genuinely works. The color is a gorgeous pink-red that photographs beautifully in natural light — which is probably why every cafe in Seoul jumped on this trend. My honest criticism: it leans sweet. If you don’t have much of a sweet tooth, ask for less syrup (“시럽 적게 해주세요” — “sirreob jeokge haejuseyo”). For most foreign visitors, though, this is a crowd-pleaser and a great photo opportunity.
3. Yuzu Honey Ade — My Personal Favorite
As a Korean dad living just outside Seoul with a kid who already claims to be a “food critic,” I had strong competition when it came to ranking my favorite drink of this experiment. But the yuzu honey ade won it for me, and even my kid agreed after stealing a sip. I found an excellent version at Fritz Coffee Company in Mapo for 7,000 won.
Yuzu (유자) is a Korean citrus fruit that tastes somewhere between a lemon and a grapefruit, but softer and more fragrant. Combined with honey and sparkling water over ice, it becomes the most refreshing summer drink I’ve had this year. It’s not overly sweet, it’s not sour enough to make you wince, and that floral yuzu aroma is something you just don’t get from Western drinks. I want to be clear: this is not a novelty drink. It’s genuinely delicious, and if Seoul summers hit 33–35°C the way they usually do in July and August, you are going to want this in your hand.
4. Black Sesame Cold Brew — Bold and Divisive
I’ll be upfront: this one split my taste-test panel of two (me and my wife, who agreed to come along for this particular stop) right down the middle. Black sesame cold brew is a rich, dark, nutty drink where cold brew coffee is blended or layered with black sesame milk. I tried it at Terarosa in Gangnam for 8,500 won.
If you’ve had black sesame ice cream or heukimja porridge before, you know that deeply roasted, almost smoky nuttiness. Paired with the boldness of cold brew, it’s genuinely complex. My wife loved it immediately — she said it reminded her of childhood desserts. I found it a bit heavy for a summer afternoon drink. It’s thick, filling, and strong. For coffee lovers who want something uniquely Korean and are willing to try something that has no Western equivalent, this is your pick. For casual drinkers or people who don’t like strong coffee, skip it.
5. Barley Milk Tea — The Sleeper Hit
Nobody was talking about this one loudly, but it kept appearing on menus and I kept seeing locals ordering it. Barley tea (boricha) is something Koreans grow up drinking — it’s served cold in restaurants, packed in school lunchboxes, and basically part of daily life. Now cafes are making a latte version with oat-adjacent barley tea as the base instead of regular tea or espresso.
I tried this at Momos Coffee in Seongsu for 6,500 won. The result is gentle, toasty, and honestly comforting in a way I didn’t expect from a summer drink. The roasted grain flavor pairs naturally with milk — think of it like a very mellow, earthy latte. There’s no caffeine anxiety, no sugar spike. It’s the perfect drink for a slow Saturday morning walk through Seongsu, which is honestly one of the best neighborhoods to cafe-hop in Seoul right now. If you’re visiting with family or someone who doesn’t drink coffee, this is the safe and satisfying recommendation.
