Me and my friends ate some good food at a backyard restaurant. Nice jazz music playing that wasn't too loud. Probably the best restaurant experience I have had in a long while, where usually you are in a loud and cramped interior environment and/or the food isn't very good. I was a little iffy at first seeing the location in a residential neighborhood but I am glad I went. Would recommend.
They must be paying off that mortgage fast if they have not already. Sounds like a really clever idea. No need to own a separate building and maintain it and pay utilities bills or rent for it. You save a lot of money. You wake up and you are already at work. Taking care of your own home is taking care of your workplace, and taking care of your workplace is taking care of your home. They'd only have to drive out to buy fresh ingredients which they would have to do anyway even if they weren't running a restaurant to buy food. Only limiting factor is the amount of parking space outside that isn't in front of the neighbors' driveways or mailboxes.
