Excellent acoustics. The entrance to the hall is through three floors (depends on how high the tickets are purchased). Even in the upper rows, everything is visible and audible. What you should pay attention to: this is still the opera house, so visitors are dressed smartly and it's appropriate here. There are buffet areas where you can have a snack during the intermission.
