My oldest and best friends are here from NYC with a rare treat... their parents. We are planning on having lunch tomorrow at around 3:30-4 pm. They are staying in Nob Hill and I need a place that is nice, relaxed, with a full bar and some SF culture, like maybe a view or in an interesting neighborhood. We'd like to stay in that region of the city, as we will be dropping off the rents after lunch and we don't want to travel too far. Price no object, need some chowhound input as we usually eat out on a budget.
