When have you chosen the price vs the quality of food.
I don't think I've ever heard some say, let's go there it's cheaper than x especially by an amount of 10%.
If the steak costs R100 vs R110 there, is the difference so major that you'd ignore which one does a better steak?
It doesn't matter that nobody says "let's go there it's cheaper" -- consumers are conscious of value.
On what basis are you assuming the more expensive menu price implies a better steak? Waiters don't typically make the food.
