We had our wedding here on July 21st! We worked with Craig & Bryan planning the wedding. They always got right back to me with any questions! The centerpieces were set up beautiful by Judy from Main St florist. The DJ & MC Kevin from Absolute had everyone dancing. Everyone loved the food and venue. Staff were very nice...Ashley made sure we ate and always had a drink in our hands. Thank you for the memories
