I would second the Michelin City recommendation; they also have a have a aramid layer for flat resistance. Have 1500 miles on a pair, no flats so far and not noticeably worn.

I also have a pair of Marathon Cross tires on another bike; they don't roll quite as quick as the Michelin City's on the road but they are suitable for most hardpack trails. Definitely the best all-purpose tire I've ever used.
