Cube Coffee Bar
Unlike the city center, the outer part of District 6, beyond the Grand Boulevard, isn't swarming with specialty coffee shops. In fact, Cube, a hip café occupying a hole in the wall, is a lonely warrior in the neighborhood, pushing the boundaries of new-wave coffee one batch brew at a time.
The options span the whole range, with both espresso-based (cappuccino, cortado, flat white) and filter coffees (V60, cold brew). The interior decorated with exposed bricks, subway tiles, and Edison light bulbs isn't revolutionary, but I'm glad they retained the original terrazzo floors. These gray-and-white square tiles used to be ubiquitous across Budapest but now fast disappearing. Once here, be sure to glimpse the Hunyadi Market across the street for a bit of time travel.
