Louder Coffee Bar is a small coffee bar between Seoul National University Station and Nakseongdae Station in Gwanak-gu, Seoul. It serves einspänner and espresso, with the einspänner topped by sweet cream, alongside espresso drinks such as strappazzato. Laptops are not allowed and visits are limited to two hours. The einspänner contains more non-coffee ingredients than coffee, so its coffee aroma is weak.
