Need weekday lunch suggestions north side of SF
I need to find somewhere for my mom to have a 70th birthday lunch on a Monday for a friend of hers who lives in Pac Heights. She would like somewhere nice but not particularly fancy -- in other words, somewhere with good food and nice enough ambiance, but not somewhere where people will feel any need to dress up. She doesn't need a private room, though that might be nice. I was thinking that something along the lines of Absinthe would be good, but I am hoping to find something closer to Pac Heights, if possible. I am almost never on that side of town and am at a loss. Any help would be appreciated.
