I am organizing my best friend's rehearsal dinner in SF for a party of 50 (locals and visitors). I'd like to find a great place to have a crab feast (Oct 24 dinner date), it being a San Francisco quintessential experience. Looking for a restaurant that can:
1. accommodate big party with private room
2. Serve GOOD local Dungeness crab
3. Be somewhat casual
4. Preferably in the city
This may a tall order, but I thought I'd give it a shot. What I'm NOT looking for is a banquet, sterile sort of environment or chain.
