Last time i went to Hongdae with ci nia my friend from backpacker korea. We were hungry but craving for easy light bites and while we were walking around Hongdae exit 6 gyeongui forest line, we found Cute Hotteok or korean pancake. And fortunately, that one is Hotteok house that i've found long time ago on instagram but i never tried!!
HOW TO GO
Hongdae MRT station exit 8 or 6 (line2)
서울 마포구 와우산로 162
they have many selections of flavour, classic melting brownsugar and peanut, greentea, hotteok with icecream, nutella choco and etc!
I bought one called ITALIA because the filling exactly like pizza, mozarella and tomato sauce super ooeeygooey inside and crispy batter outside yum!
(hope it much bigger lol)
