The 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 lunch or dinner, or 50 guests for a standing reception.  The three large skylights bring in plentiful natural light during the day. Ambient noise level is low to moderate, with an optional soundproof curtain. Best for smaller meetings, seated dinners, business lunches, presentations or lectures. The space configuration is highly flexible for seated or standing functions.

The second floor Avenue Lounge features an open floor plan with two story windows overlooking Pennsylvania Avenue. It is perfect for larger private receptions, fundraisers, cocktail parties, and seated lunches and dinners for groups of 40 or more. It is an airy, elegant space with a raised stage, two-story gas fireplace, with capacity for 65 guests at a seated event or 100 guests standing. Our most beautiful space, featuring exposed brick, tons of natural light and walnut hardwood floors, makes the Lounge the perfect vibe for your personal celebration.

Our first floor Main Dining Room is available, on select dates, for larger seated events for up to 65 guests, or standing receptions for up to 125 guests. The first floor is our only space for ADA compliant private events. Sonoma also has the unique ability to combine the two second floor event spaces into a single space with capacity up to 150 guests for a standing reception. For very large groups, Sonoma is available for a first and second floor Full Restaurant Buy Out with a capacity of 275 guests for a standing cocktail reception, wedding, or fundraiser.
