You saw it a lot in the squid game, right?
However, it is not easy to find a dalgona restaurant in Korea these days. There used to be a lot on the street.
So if you want to eat dalgona, you should search on Google Maps.
I found a few, so if you want to go, refer to the map below
Most of the places that sell dalgona are on the street, so there's no separate building
Look around here!
