Grazie's seafood pineapple salad at Taste of Chicago 2008 was fresh pineapple that burst with refreshing juice with each pineapple chunk, and it was nicely chilled seafood salad (probably the leftovers from all the crab legs everyone else was getting here).
Adobo Grill's Cochinita pibil (pork tacos) hidden away by Buckingham Fountain (but far enough away from the Budweiser Clydesdales) was the prettiest thing I ate at Taste of Chicago 2008. Brawny was passing out free towels at the event and you need them to eat this.
