I paid $9.55 (including sales tax) for a double double cheeseburger, French fries, and regular root beer at In-N-Out Burger in Prescott AZ.
“Yeah, it should be cheaper for a fast food place. But when I say “sit down restaurant”, I mean one with a wait staff. The ones I typically eat burgers at are Applebees, Chilis, Red Robin or some local brewery.”
Sally B’s Cafe in Prescott Valley still sells burgers and fries (or onion rings or sweet potato fries) on their senior menu for under $8. Food’s good and servers are friendly.
