It is actually a brand. A new brand that I never seen before. And I saw it at the Biff Square. It was a street where I took my lunch and also some street food. The ice cream stall is located at one of the street and you can only buy it take out. Instead of eating inside the stall.
When I tried to ordered by myself, the uncle that worked at that came out and helped me. So I just told him the flavors I wanted and he took it for me. It was not expensive too since one ice cream only costs around 2000 won. And I am sure it will be really worthy.
