Having been to many a diner-including one back in the '70s near Manchester, Connecticut, along with a few in a Yonkers, NY and, of course, New Jersey-I was slightly skeptical about a diner coming to Sarasota. Would it be good, hearty food or a fraud? I've been to a few places that claim to be delis but aren't really, and when I walked into the new Metro Diner , at Westfield Siesta Key, I confess I was expecting the same kind of thing.
