Does anybody know anything about weddings at the Heinz History Center? We really want to have the wedding there, but it's pricey and there doesn't seem to be any wiggle room for venue or catering fees. You have to use their caterer, and I'm concerned about their prices. Any experience with this place or ideas of how to save some money? I've already asked for off season rates, and they say they don't change their fees based on the time of year. Thanks!!
