Visited the museum during Doors Open and the restaurant upstairs during Summerlicious and I had a good experience both times!
During doors open, a lady gave an about half hour tour of the museum and she told some pretty interesting stories. It was pretty interesting even though I'm not really into pottery. The pottery classes downstairs also look really cool if you're living in the area.
The museum's upstairs restaurant was $15 for Summerlicious, and it was one of the emptiest summerlicious places that I've been to, but it was really good. The decor is very classy and the sunlight from the shutters look very nice. View isn't that great, since you're on the 3rd floor and all you see if the ROM, but the waiters give a high class service, and the creme brulee was really really good.
