Within Seoul's "kidult" community, Gundam PlaModels are possibly the most hyped-and-sought-after toys. Legos would come in second place with an equally obvious cult-like following. The moto of the Lego Group is “Inspire and develop the builders of tomorrow,” marketing the activity of Lego-building to help develop creative abilities in young children. Surprisingly, in Korea, they reach a much larger audience; 20% of all Lego sales in Korea are to adults or perhaps better known as kidults...
One of the sub-groups of the kidult community are those that focus on one item, one brand, or one character and become crazed maniacs about it. In Korean we politely refer to them as "odeokoo." There are a few worthy places in Seoul that are catering to these ‘maniacs’, they include the Gundam store, Marvel store, Lego store, and the two very Korean Line and Kakao Friends stores. See what kind best suits your likings.
