Did you ask on your invites if anyone needs different foods?! We didn't, I assumed if someone knows there is something they can't eat that they would tell us? My oh is quite intollerant of vegetarians and even more so of vegans (being a dairy farmer he likes people to eat a lot of dairy lol) and none of his friends would dream of giving up meat. Some of my friends I know are vegetatian and our main course is a grab a plate and say want you want as you go along the buffet so they are easily catered for by having the same minus the meat but I guess I'm just worried there might be people there who can't eat what we have chosen?
