Wedding rehearsal dinner in Carmel [moved from SF Bay board]
Not sure where you'll be in the Carmel Valley, but if you're not too far out, that puts you in range of most of the Carmel and Monterey restaurants. You might check some of these, all of which do large groups/banquets:
Rio Grill, Crossroads Shopping Center, Carmel, http://www.riogrill.com
Bahama Billy's, Barnyard Shopping Center, Carmel, http://www.restauranteur.com/bahamabi...
Tarpey's Roadhouse, Monterey-Salinas Highway (aka Hwy 68), Monterey, http://www.tarpys.com/
Il Fornaio, Ocean Ave, Carmel, http://www.ilfornaio.com/?page=138&am...
Stokes Adobe, Hartnell, Monterey
Further afield, but fun and with a drop-dead view (but maybe too expensive) is Roy's at Spanish Bay (Pebble Beach), overlooking the ocean and the Links at Spanish Bay.
You might also have a look at this list of banquet/group facilities (which looks to be slightly out of date): http://184.108.40.206/search?q=cache:_4...
I got married in Carmel Valley and we had our rehearsal dinner at Tarpy's. It was great, we had the whole outdoor area. It was actually a reharsal late lunch, not sure if it would be warm enough at night. We also looked at Piatti in Carmel. They have a great rooftop spot, but it was a little to small for us. I don't remember the headcount allowed there.
