We had our reception at a hall where we brought in our own food, alcohol and other drinks. Instead of buying a large number of 2-liters, we looked for a place that sold a lot of soda at a reasonable cost. Glewwe Castle Brewery is a company that sells soda in kegs - they are known for their rootbeer, but they also have orange, ginger ale, raspberry ginger ale, and cream soda. We contacted them the week before the wedding and they were able to accomodate us. They delivered the kegs to the reception all and came to get them at the end of the night. What soda was left over was bottled for us later and they brought those to us. The soda was a hit - all ages loved the different kinds that were offered.
