The number of 5 star reviews here is spot on. One would be remiss to visit Cleveland and not visit this museum. I was blown away by the collections and did not expect such an extensive, well organized, and aesthetically exceptional experience. Entering the atrium was the first indication that I was going to love this museum. The space is so inspired and comfortable, and upon further investigation, they have lots of evening events in the atrium (including a dance party, which I assume is one of their targeted activities to attract younger folks to the museum).
On a random Thursday, there were three walks/tours that we could have joined, and a lively but not overcrowded array of visitors. The cafe/restaurant was a tandoor grill... looked and smelled amazing, and there was space to eat either in The cafe itself, or out in the atrium.
I also recommend checking out the selection of films that they offer. I didn't have time o see one, but the line up included independent and documentary type listings that probably aren't showing too many places around Cleveland.
Islamic exhibit opens after the holidays (for non-members).
