You will enjoy Lumen Café if you prefer to avoid the heavily-touristed streets of the Jewish Quarter, but still get a cup of specialty coffee or craft beer in a hip neighborhood. With egg-based breakfast offerings (served until noon on weekends) and a thoughtful interior design featuring concrete and wood finishes, Lumen Café is more than your average neighborhood café. But it's the patrons, artists and neighborhood bohemians, who give a soul to the place.
Being an all-day café, Lumen can get busy in the mornings for breakfast and coffee, at midday for the €5 lunch prix fixe, and at night for basic food and drinks. The outdoor garden in the back of the space is where you might be witness to deeply philosophical discussions fueled by local beer and wine. If you go in the evening, pop in to the almost daily live concerts they host inside the hall adjacent to the main area.
Don't confuse the two Lumens - there's a smaller location around the block from here and operating under the same name, but this one (Horánszky Street) is where most of the action is.
