It's also a clarification between "I would like to, but no thanks due to these other circumstances, maybe another time" vs "No, would not like to, probably not ever." It's also giving you the opportunity to counter-offer, as it were: if you're not particularly hungry either, so maybe something more like a small appetizer and a drink?
Plus a million other options, of course.
It's not really a yes or no question to begin with, even if you're thinking of it that way.
Well to be clear, this isn't for a date, this is a common occurrence with my wife. It really is "do you want to do this tonight or don't you". It could be, "I had a big event today so the last thing I want to do is help cook", it could be "I ate a lot and I'm not hungry". I still don't know if she wants to eat out tonight.
