There are pro versions of Ghostbusters at the following locations:
Closest location to you would be Pinball Gallery (81 Lancaster Ave in Malvern)
Loco Pez - 2401 E Norris St in Philadelphia
North Bowl - 909 North 2nd St in Philadelphia
The Bar(n) - 4901 Catharine St in Philadelphia
University Pinball - 4006 Spruce St in Philadelphia
This is based on the pinball map app so if you show up and any of these are no longer there... I'm sorry.
Also, I work in Allentown and live just south of Allentown. So let me know if you are ever down to meet up and play some pinball!
