In short

Ugly Tongue (어글리텅) is a smoothie café on the ground floor of the J Block building in Songdo, Incheon. The morning after a night of drinking, before taking her child to a movie, the writer ordered Ugly Tongue's 15,000-won diet smoothie with glucomannan added, plus a 5,000-won iced Americano. Even with kale powder, the Ugly Tongue diet smoothie had no grassy taste, was gently sweet and was filling enough to replace breakfast.

Songdo smoothie spot Ugly Tongue (어글리텅, UGLY TONGUE)

I love coffee, but sometimes you want a drink that's good for you too, right?! I'd been drinking the night before, so the next day I really wanted something fresh and ice-cold that would rehydrate me and give me some nutrition! So before going to a movie with my kid, I visited Ugly Tongue, a smoothie specialty café in Songdo :)

Ugly Tongue location and parking: ground floor of J Block, Songdo

Ugly Tongue is on the ground floor of the J Block building in Songdo :) Parking is available and the lot has plenty of spaces, so it's easy to pop in for a drink or grab takeout. And if you're watching your diet or want something light to replace a meal before or after a workout, nothing beats a healthy smoothie! haha

The outdoor seating right in front of the shop was decorated with a camping vibe. In the cooler seasons, it would be really nice to have a coffee or smoothie out here ☺

Ugly Tongue menu, prices and the glucomannan add-on

I took a photo of the menu at Ugly Tongue: I ordered an iced Americano for ₩5,000 and a diet smoothie for ₩15,000! Under each smoothie there's an add-on ingredient you can choose, and for the diet smoothie I added Glucomannan (글루코만난)! I heard it's good for lowering cholesterol 😁 The menu lists in detail what goes into each smoothie, which made it easy to check 👍

You can order yourself at the kiosk in the corner of the shop, or order from the staff at the counter! I told the owner I wanted a recommendation for a sweet, refreshing smoothie, so I ended up ordering at the counter, hahaha. Also, this place is famous for its ice cream, so I thought next time I should try the blue spirulina ice cream 😚

There were lots of bottled drinks too~ and salads below!

Ugly Tongue focuses on smoothies made with fresh fruit and vegetables, so it's a café that suits anyone thinking about their health~

What was in the diet smoothie, and how did it taste?

The smoothie was what I was most looking forward to!! The diet smoothie I ordered contains:

  • Banana
  • Blueberry
  • Fig
  • Lemon
  • Coconut water
  • Maple syrup
  • Kale powder

Just looking at the ingredients, you can tell it's packed with good stuff 💜

The banana gives natural sweetness and a smooth texture, and the blueberry adds a fresh tang :) The subtle sweetness of the fig adds depth, and the lemon keeps the whole thing bright, so the aftertaste wasn't heavy!

Maybe thanks to the coconut water, it felt much lighter and more refreshing than the ingredients alone would suggest, and even with kale powder I could barely taste any grassiness. Even people who don't eat many vegetables could enjoy getting their veggies and fruit comfortably and tastily 💜 Plus, with maple syrup in there, the sweetness isn't artificial but gently, naturally sweet, which I liked even more haha

Ugly Tongue diet smoothie with glucomannan added

I also added glucomannan. It's a dietary fiber known as the main component of konjac, and it swells when it absorbs water, so it's said to boost fullness and may help ease cholesterol :)

Iced Americano taste

And an iced Americano is a must to wake me up in the morning, lol. It had moderate acidity and a good balance, and I enjoyed it a lot haha. It wasn't watery, but slightly strong, so people who like a clearly defined coffee flavor will probably like it!

When to visit Ugly Tongue

Ugly Tongue doesn't just fill you up. You get the satisfaction of having eaten healthy ingredients, so it works well as a breakfast replacement or a post-workout meal haha. If it's hard to eat lots of fruit and vegetables at once, a single smoothie makes it easy, which seems like a real plus! Lots of people are into low-sugar, high-protein and clean food lately, and I felt Ugly Tongue fits that trend well :) If you're looking for a healthy smoothie in Songdo, try a cup at Ugly Tongue haha. It feels like the day starts off fresh✨
