Cafeineo is a cafe in Gwideok-ri, Hallim-eup, on the coastal road along the sea in Jeju. It serves coffee and an ineo latte, its signature drink, and customers can have coffee and cookies while looking at the sea. The cafe appeared as a filming location for Yumi's Cells 2, so visitors can recall scenes from the drama. The sea is visible from the windows, and when the door is left open, sea breeze comes in.
