Iaian is a cafe in a converted villa between Seoul Forest and Seongsu, serving coffee and seasonal tarts. The tarts change fruit and cream by season, including bam tart, strawberry tart, and lime tart, and the basil tomato ade is made with house-made cheong. The space combines dark lighting with wood interiors and shifts into a cocktail bar mood in the evening. Coffee is brewed strong, and drinks and desserts are made in-house.
