Favourite: McDonalds.
Yes, I know, but there's usually one nearby, I know exactly what I want, the kids know exactly what they want and they will eat it. And we can be out of the place in 30 minutes and on to the real reason why we are in that part of town. I know its not the most healthy, but if we only eat there half a dozen times a year what is the harm in that?
Much rather eat there than in one of those pretentious places where the menu is all french and I come out more hungry than when I went in.
