It used to be 3-5x more than fast food.
A burger with a meal + a drink @ Wendys is like $8+. The price of fast food has risen quite a bit over the years.
I can get a burger and fries that's 10x better at Friendly's, Ruby Tuesday's or a half a dozen other franchises for about $10-12 and the only sacrifice I have to make is that I'll have to drink water instead of soda.
