with a cherry on top

"with a cherry on top" means to do things to perfection, with no details spared, and all steps carried out, up to and including the very last one, which is the most important step..

The phrase comes from "with a cherry on top of the sundae". A sundae is prepared by putting icecream in a dish, adding nuts/fruits, and pouring syrup on top. The last step is to put a bright red cherry on the very top of the syrup covered icecream. A sundae isn't really a sundae without that cherry on top. With the cherry on top, the sundae is now prepared to its perfection.

有一顆車厘子在頂部。

我認為本句前面應該有些英文字，例如cake。
