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!

Hello!

I’m searching for distinctive venues in San Francisco for an event in November. They should have the capacity to host more than 400 attendees. Does anyone have any recommendations?

I’m on Vendry going through a ton of restaurants in SF - while I’m doing it maybe someone can recommend a recent experience with a private room or secluded area for a 10-12 people dinner? Business but intimate and friendly, not too posh. budget $3500 (realistic for SF?).
