Hi G.,
Try the Freedom Hall and Gardens. It's in Santa Clara near Great America. They have a very resonably priced, almost all inclusive deal (the place, centerpieces, food, drink, cake, DJ, wedding coordinator) that will work for you. It's a deli during the day, but is amazingly transformed for the wedding - plus you can have the wedding outside (in the gardens) or inside. And the food is excellent!! Please check it out - they have pictures you can see from other weddings too. I think you can just Google them... Congratulations and I wish you the best!
S. H.
