Eventective.com is a search engine that enables you to select a geographical area, preferred distance from that area, and the number of people and then receive a listing of locations as well as their event space, capacity, and square footage.
Click the link for more info and you'll see a more detailed description of the facility's amenities. Click the link for more images and you'll see shots of the inside and outside.
Looks like a very handy resource!
