This is one of my favorite places in the valley - there's always something new here, and it's big enough that I don't often get to walk the entire thing in one visit.
If you visit often, I recommend a membership. $75 gets you in for free, but the $200 level gets you invited to all 4 private exhibition event evenings. The $100 level gets you invited to two.
They host frequent lectures and all kinds of interesting events. You can always find something going on, on their calendar.
Some of the permanent collection I am very fond of... Seeing the same exhibitions a bunch of times is kind of like visiting an old friend. There is always something new to appreciate. The rotating and visiting exhibits are always well presented, as well.
Arcadia Farms is a fantastic place to eat, the healthy slow food really fits. I mean, what do they serve at the Met in NY? They have a shitty cafeteria. We have Arcadia Farm bitches! OK so the Met has a huge Egyptian temple and Dutch masters paintings, but we have this weird reflective black plastic concave/convex thing and a dark room full of hanging LED's and mirrors.
There is more culture in Phoenix than the out of date yogurt in your fridge!
