Some resturant/ fast food chains are pretty good at providing details on the drawings. I used to wire lots of those famous "yogurt" shops with the letters for a name. They went overboard on drawing out 3-D details on the soft serve electrical and plumbing hookups. It was great because the plumbers could not get away with the usual practice of ignoring the electrical stuff on the plans and just ramming in pipes anywhere they liked to. Resturants without a good game plan are the reason I started to get bald.
