The second floor Private Dining Room is our most intimate and secluded private event space, located in the back of our second floor. The room has capacity for 40 guests for a seated or standing event, with a ceiling height of 12 feet, highlighted by skylights that bring in plentiful natural light during the day. Ambient noise level is low to moderate, as the Private Dining Room also contains its own bar and music controls. It is our recommended space for smaller meetings, seated dinners, business lunches, presentations or lectures, and the perfect room for controlled-access fundraisers and media events. The room can be set in many different arrangements; ask our event manager if you have specific set up needs and we will do our best to honor them. 

The second floor Avenue Lounge features an open floor plan, furnished with contemporary sofas and club chairs, and is perfect for larger private receptions, fundraisers, cocktail parties, and can even host lunch and dinner event as well. It is an airy, elegant space with a raised stage and two-story fireplace, and has capacity for 50 guests at a seated event and 100 standing, with a ceiling height of 9-20 feet. Ambient noise level is low to moderate, as the Lounge is on the restaurant’s second floor, away from the main dining room, and contains its own full bar and music controls. It is our recommended space for larger cocktail receptions, fundraisers, media events, wedding ceremonies and receptions.

Our first floor main dining room is available for larger seated events for up to 50 guests, or standing receptions for up to 100 guests, on select dates.
