We've had just horrible service at the Ram with only four in the party. I can't imagine how "dicey" it may be with 100. Also, keep in mind that at Bob Chinn's you're going to be served VERY informally (think paper plates). Buca de Bepo is in the same general area, altho I have never been there. If you come a bit further south, Allgauers is an old standby, and probably could handle 100 with no problem.
