The Tull Family Theater
418 Walnut Street, Sewickley, PA
100% positive
Directions: Inside to the left
Comments: Not sure if they'll let you in if you aren't there to see a film, but the restrooms are in the lobby before the ticket check stand, so it should be fine. May have to buy something from the snack bar if they want you to be a "paying customer." Excellent popcorn and slushies, btw.
