What kind of restaurant is this?

I told Jonah on Tuesday that we were going out for lunch. He immediatly said "hotdog". I said sure, you can have a hotdog. (If I ask him what he had for breakfast, he'll also say hotdog. So although I knew that he like hotdogs I wasn't too concerned about it but instead was aware of his limited vocabulary). But wouldn't you know, as soon as we sat down at the diner he told the waitress"hotdog". She yelled at the lady in the back (owner? manager? another waitress? who knows) who said something like"we're all out". So the waitress instead brings a totally yummy looking grilled cheese that I was willing to trade my chicken sandwich for. Jonah said "hotdog?". So instead of eating Jonah flirted with the ladies in the booth behind us and watching the airplanes out the window (we were at the Airport Cafe). So we packed up the sandwich and stopped by my friend Claudia's house who was serving hotdogs for lunch!! Jonah again said "hotdog?". She happily traded her hotdog for his $3 grilled cheese. I'm pretty sure that he thinks he got the better end of the deal!
