usually most graduation parties are like a open house, where people come and go (or like us have double parties to attend)...i'd use some throw-away sterno heaters, and an iced tray and have everything ready, including the usual cake. use dental floss to cut it without "messing" the design too much...

i'm so hungry right now i'd love to have your anniversary brunch! add a tray of mini-muffins, or small bagels and whipped cream cheese. that should help anyone with a egg intolerance...it might be easier to serve mini juices (costco or sams) keep them on ice in a tub...
