The last time I did it, I bribed a friend with free food and wine. I had him set up in a corner of the kitchen, out of the way. Before service, we layed out a small piece of black marble, put a dish of food on it, and worked on the lighting and focus for a while until we were happy. Then, during service, as I expedited, I would "style" each particular plate of food we wanted to shoot, as is was ordered, and quickly pass it off to the photographer. Because we already had the set-up the way we wanted, each plate only took about 5-10 seconds to shoot -then out to the table. No waste, no cold food, it worked out really well. The next day I had him come in for a few staged action shots: floury hands rolling out pasta, brandy flaming in a saute pan, blah blah blah. I let him bring his girlfriend in for a couple of dinners, done deal.
