You can still work to improve city mileage by only accelerating enough to get you to the next stop and trying to time the lights. It can be a pain sometimes, and people will get annoyed with you at times. Planning routes more efficiently can help a lot as well. Sometimes it's better to go a few miles out of the way because the route is more FE friendly.
That said, when I do more city driving, my mileage does take a hit, but I still manage better than EPA mileage. The ratings do give a range for city and highway mileage now though, and I figure you can hit the higher end of the range if you drive smart.
