I've been to Heinz Hall multiple times before for other events, but most recently I went here for the Lauryn Hill concert. You can't miss how beautiful this venue is with all of the intricate paint details, shining chandeliers, and velour red seats. The maintenance of this place is amazing! Despite the classic and look feel of this place, the sound was still great! After a few adjustments, we could hear Lauryn Hill and her band clearly from the balcony or "dress circle".
Be prepared to pay at least $10 for a drink on a concert night. Also, they may give you a plastic open cup that you can drink outside the main hall, however there's another cup for a extra charge with a lid that you can take inside the main hall.
