Cups cups cups! ...and what to put in them

So on a whim I went out and bought these gigantic ACME cups because they were cheap and my wife really liked the colour. (They are 350ml)

Now I have no idea what to make in them!

Do I need to just get a bigger basket say 22 gram? Massive long black/cortado. Make you throw up from all the milk cappuccino?? Or are they just for looks...
