Enjoy a glass of wine from our extensive wine list as you sit by the cozy fireplace in the fall and winter. In the spring and summer, soak in the sun on our patio next to The Courtyard fountain while sipping on one of our specialty martinis. Choose Siena to host your next special event. Siena can host rehearsal dinners, weddings, business meetings, holiday parties, and any other gathering you might have. Siena is the place to be in Castle Rock for Happy Hour.
