Coffee House Design (and gas line - still!)

As of this weekend, the gas line wasn't hooked up yet, so I'm not sure what's going on with that.

The kids are back in school today, so everyone is feeling well again.

Now that the first floor is completely gutted, PC and I are trying to figure our layout for the Coffee House innards: the kitchen, the counters, the workings, etc. We have come to the conclusion that in order to get it right (meaning efficient and welcoming and building/health code approved), we are going to need some help.
We'll proceed with the utility fixes and get started on the ceiling while we start reading up and asking advice on restaurant design. I've been in contact with a Coffee House consulting company who can give us a hand with the coffee service aspect. Now I need to do the same with the food service side of things.
