Riverbell Coffee is a small roastery cafe in an alley near Sadang Station in Seoul. It roasts its own beans and serves a blend espresso of Ethiopian Yirgacheffe and Sidamo, Vienna coffee, and drip coffee, with a choice of three beans. Inside are an Aegister 4kg roaster, a British Fidelity amp, and Bose speakers, along with homemade tiramisu. Seating is limited, so tables fill up, and the gaps between tables are narrow.
