Q. For 60 people attending the rehearsal dinner (dressy but not formal), how should the tables be arranged to promote conversation and have guests be comfortable?
A. Try nothing but 8' rounds - with yours in the very center of the all or try a couple of "U" shaped arrangements with seating on both sides of the arms of the "U" and only the outside of the base of the "U" - have a "head table" of a straight line with seating (Like on stage) only on the side facing the two or three other "U"'s - bride/groom, moms/dads, attendants at the head table (or if rounds keep the maid of honor and bestman with their "significant other" at the head table with the other attendants surrounding you). Where ever you are having this - whomever is organizing it - should have some good insight and suggestions that best suit the location - and the availability - ask! It's your money.
