I'm having a buffet at my wedding involving several choices of entree, including one vegetarian entree. There are also two vegetable side dishes, as well as a cheese platter and other things vegetarians can eat. Should I still get separate meals made for my vegetarian guests to ensure they get enough to eat, since presumably some non-vegetarian guests might still want to partake of the vegetable dishes? Or should I just make sure that when it comes to deciding which tables go in what order to get their food, place the ones with people who have strict dietary requirements closer to the front of the list?
What about stuff like lactose intolerance? I know there are several dishes (including entrees) which don't have high lactose content, so there should be enough food for people who are lactose intolerant, but should I get separate meals made for them just in case?
