You know what you want you want when you walk in the restaurant or you would not be there. You wanted a burger/fries or hot dog. They are served hot off the grill, hot fresh french fries that you see being made. Fast service, clean tables. Chain quality so no mater where you are you get a consistent product.
Pro: Nice lunch for the day after the possibly over served night
Con: One temperature for burgers, well done. No safety risks but not my medium rare temp
I'm not a frequent flyer (for most fast type chains) because i', the square peg for the round hole for food orders
