The staff were very kind. I ordered the squid ink baked bread, and it was delicious😋! A great place I'll definitely visit again when I'm in Seongsu!

The chocolate mochi was absolutely delicious! It was chewy on the outside and crunchy on the inside, not too sweet, and the nutty aroma spread through my mouth—it was the best.

I visited around 10 AM on a weekday and was able to get in without waiting. The mountain-shaped bread topped with powdered sugar that I saw on Instagram was delicious. You can take it to go as hand luggage. I ate the cream-based and Shine Muscat breads at the airport.
