Personally, I think this place is WAY overpriced, but my daughter had a blast. She made a really cute bowl with her aunt, and we have something special to remember her aunt's visit to Pittsburgh.
They have various discount times so I would suggest looking into them. You have to pay a sitting fee and pay for the piece itself. Even a small mug is about $10. We don't understand what we're paying for here. There's nothing special about this place.
We're going to save this place for special occasions! We've got art supplies at home. :)
