There wasn't a fee, everyone there was super nice and friendly.
I t s free to get in.
Just tips. The men there were amazing so much knowledge.
No fee, they accept tips
There is a donation box when you first walk in. There is no fee and like every one else said, the staff as super great. You should bring cash as there is stuff to buy that is very cool. When I was there a few months ago, their credit card machine was not working so I would bring cash.
