Instant & Fogas Ház
Instant & Fogas Ház isn't so much a typical ruin bar as a massive venue featuring more than a dozen bars and several dance floors. This enormous building with a crumbling facade dates back to 1861, when this area was part of Budapest's Jewish Quarter. Instant & Fogas may not be the best place to experience the ruin bar ambiance, but head over here if you're in the mood for dancing because other ruin bars offer little space for moving your feet.
Drinks have become pricier over the years, meaning that it's mostly tourists who come here; the place is especially popular among fun-loving bachelor party crews, in case that's not (or it is) the crowd you care to mingle with. On Friday and Saturday nights there's often a line to get in. With a separate entry but inside here is also Lärm, Budapest's leading techno and electronic club.
