The food gets cold as soon as the dish is placed on the table. They tend to put the pots in the warming drawer and dish up from there, hold for seconds, etc. The warming drawer does a better job of keeping warm because it heats the air around the pot, and a low setting on the stove doesn't. An oven with a keep warm setting that's low enough could suffice, but many only go down to 250, and that's hot enough for the food to continue cooking.
