My blueberry/pineapple "delight" came in a small cup (demitasse size). And my, I must say that I have never thought of the IC logo in the term you've described it! Judy Chicago's plates were furthest from my mind...
With regards to the room location, my res did show City View shortly after booking (I am sure that was not an option displayed on the Award Room choice menu), so while they may not upgrade Ambassadors by room category, it is likely we still get a better view pre-assigned...assuming this would be considered the better view, which I did.
My coffee cup gift did have a second insert sheet, the one featuring a collectin of teddy bears. Still don't know what their connection is with the Strings. And now that you mention it, I do see a teddy bear marching up the street behind a samurai in the classic floating world print I am using with the cup.
Got back too early for the deep discount, but did pick up a nice selection of sushi for about Y1100 at one of the stands in the lower level food market. (Wondered if I had seen the same fish toppings very early that morning as I meandered about the Tsijuki Market.) But did explore the upper level at Isetan Queens on Saturday before heading off to explore the curiosities of Harijuku and Shibuya, including the Tobacco and Salt museum (which happened to be free that day).
