Where to go for dinner after our small wedding?

Hi Chowhounds,

I'm looking to you for help. We would like to take eight guests to dinner after our very small, simple wedding at the end of the month. Four of us are vegetarians and the others are highly carnivorous, so both meat and vegetarian options are necessary.

Anywhere in SF is fine, and it would be great if we could keep it to a $20 maximum on entrees. Ideally the environment will be warm and inviting, and comfortable for a party of ten--the point of the evening will be to enjoy a good memorable meal with our closest family and friends. Please help if you can...thanks!
