100% AC and city driving will certainly put a dent in your mileage.

Do you have a previous vehicle you've driven in the same manner and kept a MPG history during the same type of conditions for a comparison?
Also, you might consider the gas you're using. I find that I can consistently get better mileage using 93 octane Amoco gas. I'm not picky about my gas necessarily, but if it shows better results than 92 octane Go-Mart gas, then I'll buy it. I believe the Amoco premium may not have ethanol hence the better mileage.
If all else fails and your driving habits warrant better mileage, you may want to have the dealer take a look.
