WERK Roasters is a roastery cafe in Gwangalli that roasts its own beans and serves espresso, filter coffee, and lattes. The beans include Guatemala Geisha for filter coffee and Baby Blend for espresso, and staff explain each bean so customers can choose by taste. The order area and the drinking area are separated: coffee chosen on the first floor is drunk in the second-floor hall, which has church-style chairs. The stairs down to order are dark.
