Need weekday lunch suggestions north side of SF

[pickles210]

Hi Chowhounds,
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.
Thanks!

You might want to check out Spruce. They are located right next to Pacific Heights. Nice ambience and they are open for lunch on Mondays.

Thanks for the suggestion. I've been to Spruce once for dinner but did not realize they had lunch. Thanks again!
