I've never had it, but I think Dan Tana's (http://www.dantanasrestaurant.com/hom... ), is supposed to do a good version of this dish. (Note that Dan Tana's is one of those places that has both admirers and detractors on this board, both of whom seem to feel very passionately about their views.)
Gets mixed reviews, but Peppone has a nice spicy one.
San Gennaro Cafe in Brentwood
Guido's is more reasonably priced.
Vitello's has it, but I'm not a fan of this place.
