Best takeout cocktail?

I picked up takeout from 100% Taquito a few days back. They make the best Paloma I've ever had, and I was happy to see it on the takeout menu. But how good could it be? They offer a salted rim … on a styrofoam cup. Surely that can't work.

But some genius at 100% Taquito made it work. And it was a great Paloma.

So what are the best takeout cocktails out there?
