Greystone Castle is a breathtaking venue for your event. We (Wed Society Denver + Front Range) recently held our Cocktail Social here and it was a truly magical evening. Jacqueline the owner & executive chef is absolutely wonderful and so easy to work with. I can't recommend this beautiful & iconic venue enough!
