Hi B.,
Check out the online Birthday Party Guide at www.kidwinks.com. You'll find some featured places, and toward the bottom, in the yellow area, you'll see a link that says "Click here for a list of all birthday party places". That link will give you a list of a few hundred area birthday party places. If you become a member of kidwinks, which is free, you can then sort that list in order of distance from you house.
Here's the direct link to the Birthday Party Guide: http://www.kidwinks.com/ForKids/6/KidsBirthdayPartyPlaces...
Kidwinks is also a fabulous resource for finding things to do with your kids. The Events Calendar is full of kid-friendly events, the Ongoing Activities Section is a great place to click through for ideas on indoor/outdoor activities, bike trails, museums, nature centers, etc. In the Restaurants Section, you'll find a Kids Eat Free Calendar - just click on a day to find out where kids eat free (or cheaply) on that day. There are many other specialty guides you'll find, too: for Indoor Play Areas, Halloween, Fall Fun, etc.
Have fun and good luck with the party!
J.
