Tiramisu I had from the Metropolitan Market in Seattle, WA.  A little sweet, but overall the best I've seen and taste so far.

Edit 5/12/2013

From the Metropolitan's Market Calendar Newsletter 5/1/2013.

"Made locally and created by Gelatiamo, this
tiramisu is made by third-generation Italian
baker, Maria Coassins, using an original recipe
with fresh sponge cake soaked in espresso and
a touch of marsala. Finished with marscapone
and chocolate, yum! "
