Crest Coffee Bar is a coffee roastery in Busan that serves espresso and filter coffee. The Ethiopia Sidamo Bensa Kokose is a light roast with fruit acidity and floral notes, and the flat white comes with milk at a moderate temperature and fine foam. The space is open, and the menu also includes Earl Grey iced tea called Crest Ale and lemon cake. Drip coffee is brewed with care and arrives a little later.
