Simply outstanding. The permanent collection is a fantastic mix of ancient, classic, and modern art. The collection is balanced and totally engaging. I went with my sister, who typically gets bored in large museums, and on the way out she marveled that she loved everything and wasn't bored at all. Trust me, that's high praise coming from her.
I was lucky enough to be in town while the Jean Paul Gaultier exhibit was in town. It was SPECTACULAR. The special exhibit cost $15, but it was worth every cent.
Best thing? The magnificent and huge permanent collection is FREE. World class art for free? Yes, please!
