Wow, Leo, that gives an entirely new spin to cheese cake that I wasn't aware of!
There are places that sell some pretty good cheese cake pre-sliced, with a bit of waxed paper between each, all frozen. Sam's Club in the U.S. has them. I scoot past that case in a hurry, it is awfully tempting. But if you want some really good baked goods (their specialty is fruit cake, but they do some very nice cheese cakes) then visit the Colin Street Bakery. They ship around the world.
