You know, I look at that sign and I flinch too.
Then I realize that this weekend we ordered from our local LaRosa's and we paid $6.39 for bacon cheese fries.
The 60 cent markup at KI for the park's similar product doesn't feel like that big of a deal. (and I'd be willing to bet the serving is bigger at the park)
Those fries suck too. They USED to be GREAT, but over the last several years the quality really took a dive. Shame too, it was the best snack in the park.
