The most beautiful food shots, are that of food that's not edible. Eg, the turkey you see in food ads is _raw_, the browning of the skin is done by a blow-torch, the mash potatoes is Crisco, the steam from the coffee is dry-ice.
I saw an article about the top food photographers, and it's as Dave says, 4x5 + digital backs - keep in mind you often see pictures of food blown up _really_ big such as on the side of trucks. A plate/dish of food closeup, would require stopping down pretty heavily since you really cannot use movements too much - the OOF areas would look wierd on a food ad. The reason for a 4x5 is just for the pixel count.
The article talked about the photographer, the art director, the food artist and/or director. So literally 4 or 5 people just to shoot food.
So for Stephanie, try to get a nice table setting with lots of window light, but not direct sunlight. Use an SLR, tripod, remote release. For a website, even a 2 or 3mp digicam might do, since the extra DOF is now a benefit. BTW, you'll probably want to do it with the food _cold_.
