What timing ... I am in the middle of such a job!

Make your drawings, and go over them in extreme detail with the customer. Pay particular attention to the 'beverage' area and the coolers.

The beverage area will likely need 11 receptacles, on 8 circuits. Go to a similar business, and look at the equipment. The soda fountain will likely need three (but they can be on same circuit): under the counter, over the counter, and neat the top (for the ice maker).

The cooler will need power inside the cooler, power for some serious refrigeration, and they'll want to hang beer signs.
Since the cooler will likely be added to the outside of the building, routing pipe and sealing your penetrations may be an issue.
The health department may want all your pipe spaced off the walls; mineralacs ought to be enough, but some guys want more.

ID every circuit before demolition begins. Many circuits are in sealed off pipes, and are a PITA to identify after the saws-it-all crew chops them off at floor level.

Get the customer to initial the plans that you submit with your permit. I guarantee that they will suddenly discover the need for many additional receptacles after the inspector leaves. (They're trying to scam both you and the city).

Finally, don't forget the phone / data / alarm stuff. They're sure to have an ATM, and that will need a phone line.

They'll also want some sort of door chime. Run power for it, near the door.
