What is the plural of Gin and tonic?

While "gin and tonic" is a singular item, it's not a single word. So, it's not quite like "cat" becoming "cats."

There are a few ways to approach this:

* Multiple drinks: The most straightforward way is to simply say "gin and tonics" when referring to more than one.

* Treating it as a unit: You could also say "several gin and tonics" or "a couple of gin and tonics."

It really depends on the context and what sounds most natural.
