We are planning a family get-together for Christmas Day in the Bay Area, but our hard-working son will be on call and probably will miss it, alas. So the plan is to have Christmas Eve dinner with him and his SO. We don't want anything fancy; casual and fun is good. Anywhere within an easy drive of San Mateo would be fine; ethnic ok. I've asked him for recommendations too, but since he's only lived there about six months (and works a lot so doesn't go out much). So I said I would ask around for suggestions as well. Last time we visited a few months ago we noticed a few nice looking places near his apartment in what I guess you would call "downtown" San Mateo. Can't remember any specific names, but the area had a nice vibe. Any ideas?
