Quoted from JodyG:
Breaking news for those that like modern pins... Round1 Bowling/Arcade is coming to the vacated Sears space at Park City Center in Lancaster. They typically have up to 8 new Stern machines at each location...so Lancaster will finally have a place to play more than one modern pin in a single location! Sweatpants optional.
The Round 1 in Exton doesn't have any pins (I haven't checked in a while though) and was all video/redemption games.
