This is where you go to paint a ceramic piece. So the way it works you buy a ceramic item (8$-100$) plus you pay a fee per hour per person. Depending how long you stay there, and how big your piece is, it does get really expensive.
They do offer food, I am not sure I would trust anyone handling pottery with sandwiches or wraps, but they do have drinks and a outrageous price for a can of juice or coke.
Go for the pottery, but not the food, eat a good meal before, then you can go and paint, and go eat again after.
