Looking for restaurant recommendations that are open on a Sunday night (7:30 PM), mid-to-upscale for ~9 people in San Francisco (ideally downtown-ish area). Some of the places I've found that look great aren't open on Sundays!

Looking for a venue in Silicon Valley (probably not as far down as San Jose) for about 30 C-suite executives. Can be a restaurant (buyout or private room), cultural institution, winery, etc. Open to any high-end ideas. Thanks!
