The quote you are thinking of is from the film Pulp Fiction (1994).
The character Vincent Vega (played by John Travolta) says:
"That's a pretty f**king good milkshake. I don't know if it's worth five dollars but its pretty f**king good."
The $5 price tag was considered very expensive for a non-alcoholic milkshake in 1994, which is why Vincent was initially skeptical and needed to taste it. Earlier in the scene, he had asked Mia Wallace:
"Did you just order a five-dollar shake? ... You don't put bourbon in it or nothin'?"
although it had only been two short days since the wolfs visit to the castle,he longed to see his princess again... so he mustered up his courage and ventured into the scary woods...as he neared the castle,he saw his beautiful princess sitting in the windowsill wearing a pink negligee and a sweet smile upon her face..she was holding a bowl of warm cinnamon glazed peaches she had made for him....she saw the wolf and stood up,put the bowl on the windowsill and the negliee fell to the floor
