The eggplant slice at A Slice of Brooklyn is an odd little thing of beauty, a quirky little play on the standard-slice-as-culinary-platform motif. It's a funny-looking ensemble: a quartet of mini-rollatini that appear to have fallen off a platter of hors d'ouevres at a black-tie gala, sitting somewhat incongruously atop one of the Slice's fine plain slices, but it works. $3. Mmmmm . . .
