    Before it became our beloved event venue, the historic Crystal Plaza was originally a residential mansion. The initial Livingston, New Jersey-based residence was built in the late 1800s by famed architect Stanford White, who was responsible for designing the Tiffany building on Fifth Avenue, the original Madison Square Garden complex and the arch at Washington Square Park in Manhattan, among other landmark structures. While the restored building has since been reincarnated as one of the leading wedding and event spaces in the tri-state area, it still maintains the feeling of its 19th century grandeur, making it a distinct and picturesque setting for special days of all kinds. Our impeccable, white-glove service begins the moment you arrive. Crystal Plaza hosts only one event at a time, ensuring that our dedicated team focuses singularly on you and your every need. From the elegant Grand Ballroom boasting numerous chandeliers (how the Crystal Plaza name came to be) to the lush gardens that change beautifully with the seasons, there are myriad backdrops to complement your wedding, social affair or corporate event. Your event is more than just a moment in time for us—we aim to leave a lasting impression that’s filled with joy and satisfaction.

The property served as a stagecoach stop and inn for 152 years before Louis J. Falzarano Jr. and his wife Theodora acquired and restored it, reopening it as David's Country Inn in the spring of 1978. Following Louis's passing in 2009, their children Christopher and Jordan assumed management alongside their mother, continuing more than four decades of family stewardship. The inn operates exclusively as a wedding and private event venue, with a defining commitment to hosting only one celebration per day. Inside, the mansion features a two-story ballroom, wood-burning fireplaces, antiques, and a stained glass ceiling. Both indoor and outdoor on-site ceremony spaces are available.
