Sat early pm dinner, 12 ppl ranging age/tastes, nice but fun

[mountainmama]

Please help! I am returning to SF for one day to have a post-wedding celebration (9pm, at the neighborhood bar my fiance & I used to frequent in the Mission). My fiance's parents want to take out the families for a celebration dinner before the big party begins, probably around 6pm. 12 people, ranging in age from 17 to 80, from vegan to carnivores, from exotic tastebuds to polite-society-southern-casserole types. I haven't lived in SF for over a year now so am a little behind on what new places have cropped up, but I do know that we need some place nice enough to justify a wedding celebration dinner, casual & big enough to seat 12 people so we can talk jovially but not have to shout to hear one another, preferably with vegetarian cuisine (for me, the bride-to-be!), and not so expensive that we will totally break the bank (can we save a few bucks to buy drinks for all our friends that night?). Does such a place exist? I am not strict on cuisine type, nor on neighborhood -- though in the Mission would be nice (and is what I am most familiar with as my old place of residence). Here are my ideas so far but please add suggestions or narrow mine down!

Green's
Ramblas Tapas
Slanted Door
Luna Park
Myth
A-16
Slow Club

Thank you! Oh, and nothing too heavy/garlicky. I don't want anyone to have indigestion when we are trying to party the night away. :)

The places you list seem all over the map to me, both literally and figurately (I wouldn't want to have to transport a group such as you describe from North Beach to the Mission on a Saturday night!), so perhaps it would help to know why you picked these? In that regard, you have a pretty big price range there; should we interpret that to mean that money doesn't matter?
