It's a nice café in an industrial area. But it is a very touristic place, I wouldn't go out of my way to come here.
The pastry is the same type of Korean padtry you find anywhere. The drinks are good. But nothing that throws me out of my chair. The atmosphere is very nice and it is a very cool place

The store was very crowded, there was a long queue, the signature pastry tasted good but the drink was just okay for me. The store's design was pretty nice though.

Get there within 30mins of the opening time or come after maybe 1.5-2 hours after that for the 1st seating to be over. The queue is long to pick out the pastries and order drinks but there’s always a staff around to guide everyone along. Food is good and coffee is great too. Worth the wait.

Comfortable and cozy experience if you know where to be seated. The pastries and drinks itself, Decent but not mind blowing as perhaps the hype seems to portrayed.

If you want a simple cafe visit with a couple of pastries and coffee, I'd visit here again, more so than the Anguk branch. More spacious and more seating areas.
