My friends Traci and Doug had their reception where Traci works, at the Moss Landing Marine Lab. Located north of Monterey off Highway 1, it is primarily a research and education facility. However, you get a great view of the bay from the back of the building, and the landscaping is done with native California plants (neat if you're into that sort of thing).
Moss Landing itself is very tiny, primarily consisting of the marina and a small conglomeration of a couple restaurants and some antique shops. I didn't find anything I was dying to buy, but the prices did seem to be good for the various antiques.
