They have a couple kits set up that they will let you play as long as you are gentle and don't go crazy. They have more electronic kits than acoustic, and they will probably ask you stop if you're there for a long time and don't seem to be interested in buying. But they are usually pretty helpful. As long as you're not a jerk, I'm sure they'd be cool.
They will allow you to do lessons on the drums. Or I think you can rent time to play them on your own I believe.
