Yeah, go to the Pantheon, and then you can go around the corner to the New Copper Penny, or whatever meat market is in there for the reception.
Actually I have been to the Pantheon for a guy's 90th birthday party. It was ok, and it has easy freeway access to I-205 at SE Foster.
Banks and churches are another place you can rent. I think a church would charge more. Do look into the church at the entrance to Oaks Amusement Park, I know it ain't cheap, but it isn't actually a church, it was once, but it is specifically for renting out for things like weddings. Then we can all go roller skating!
