Mind, there are historical examples of this - you don't want a huge bunch of hungry poor folks, zombies and skeletons or no. While they make excellent workers and meatshields, I'd still bet on the hungry mob, if there's a couple of semi-intelligent people directing it.
Examples of this are of course France and Russia. The latter proves that even though you may think your ruler is a good, if things end up shitty enough, you _will_ revolt, and then the ruler finds out that though you may be able to amass wealth, power is a very volatile substance, and wealth which cannot be used is worthless.
Personally, I think people would oppose undead cooking stuff - I won't even mention zombies, but skeletons could get a bit powdery... Besides, they are not "arteeests", so to speak. You may be able to direct them to cook, but it seems like something which requires a bit too much looking-over-shoulder management. Easier to tell them to "dig up dirt here, throw it over there. Stop when the pile is this big", "run here" or "build a wall like this, from this stick to that stick. Stop when you run out of resources". In other words, use 'em for simple, menial tasks which basically require muscle. When creativity and taste buds factor in, they become less the ideal choice.
So, I imagine a skeleton torch-lighter vanishing from its post, coinciding with a string of bizarre murders in a foggy city in a gas-lit fantasy world. Must be something wrong with me. (Also, Undead. Barber. Turned Sentient.)
