If you're looking for something to do in the city other than hit up a mall, walk the streets, club or lounge around in a bar or cafe, why not visit the walk in pottery classes? Gardiner offers 2hr walk in classes on Wednesdays, Friday and Sundays. You get to play with all the clay you can handle, and there are lots of staff on hand to help you out along the way. You're completely free to make anything you want without feeling like you're in 'pottery making 101'.
Just beware - the costs add up! Consider general admission ($12-15) + $5 (per item) to fire up your creation + $5 (per item) to glaze your creation so it's pretty. If you make one to many...like a cup and a spoon (which I made my first time, and am very proud of might I say), it could run you upwards of $25 minimum!! But at least you can scream and shout "look what I made!"
I haven't spent too much time in the gift shop or the rest of the museum, for fear I might break and and therefore have to buy, but from what I've starred at from a distance, there are some very nice pieces and great inspiration for your own work. The staff are pretty friendly too!
