Wanna to know where you found those names? and do you want to name those drink in menu with chinese?
Cos might have thousand meaning for the Mixed Juice/Drink which the ppls named it.
"Tropical Cocktail (non-alcohol) "---could be means that, mix with tropical juice like mango, guava(番石榴), pineapple etc. Cocktail in this term might means mixed like alcohol drink but replace by soda or other else to favour.
"Orchard and Exotic Fruits Juice" might means 異國果園果汁.....only juices, could be mixed with some unusal fruit juice (but you know, some foreign may think 荔枝, 榴蓮 are very exotic fruits)
So, pls advice for your propose to translate, for drink menu , BK mamas could suggest some chinese name for those.
If you just wanna know roughly the meaning in chinese, pls provide some more details in the content.
We will try our best to find it out.
