"Two Can Dine for $14.99" as incentive to eat at Swiss Chalet? And for just 2 quarter chicken dinners (quarter chicken plus french fries)?
Looking at my local online flyers, $10 will buy 6 quarter chickens (or a 3lb whole chicken) and $4.47 will buy 3lbs of potatoes.
So if you spend the few minutes it would take you to roast the chicken yourself, 6 can dine for $14.47 (or 2 for $4.82).
(And if you want to buy whole chickens and roast them up the effort, as evidenced by this simple recipe, is minimal.)
