Ongeundal (which translates to “Humble Moon”) is one of the most popular — especially for its cruffins, the croissant–muffin hybrid that locals can’t get enough of.

The café itself is huge and spread across two floors with a rooftop terrace and an outdoor garden. The interior has that industrial-Seongsu vibe: high ceilings, concrete and wood accents, and a mix of seating from tatami-style floor booths to balcony seats and even steps by a small pond. It’s the kind of place where you could easily spend a whole afternoon.

When you enter, grab a tray and tongs on the first floor to pick pastries from the display — they’re all beautiful, from croissants to cakes and donuts. But the real highlight is the cruffins, baked with flaky layers and filled with cream in the center. Popular flavors like Grapefruit Earl Grey, Peanut, and Chocolate tend to sell out quickly, so come earlier in the day if you want the best selection.

Drinks range from espresso (₩5,000) and café lattes (₩6,000) to refreshing non-coffee options like Ginger Pineapple Ade or Lemon Chamomile Ade (₩7,500 each).

💡 Tip: The cruffins are the star here — if you can only try one thing, get a couple of flavors to share.

What to Order:

• 🥐 Cruffin (Grapefruit Earl Grey or Peanut) – the most popular flavors, often sell out fast.

• 🍫 Chocolate Cruffin – rich and indulgent.

• 🍩 Croissants, Cakes, or Donuts – all beautifully presented.

• 🍹 Ginger Pineapple Ade – a refreshing non-coffee option.
