What are restaurant expenses as a percentage of the total? -

For example, on an average, how much of a percentage would a restaurant give as taxes, or for labor, or food costs. I m trying to do a paper on the economic prospects of retailer s co-ops which operate like franchises.

I ve asked the proprietors of good restaurants. They say about 20%. Franchises may have different numbers. This is the kind of research you would be well advised to do in person.
