Uno così = one like this/that
If you only learn one phrase, learn this one. It will get you through many a situation. I use this phrase all of the time when I'm in Italy. In a bar for breakfast or in a pasticceria (= cake shop) or a gelateria (= ice cream parlour) and I'm not sure of how to ask for something, I just pull out this phrase and point at what it is I want. Works like a dream, every time.
It doesn't need to be just for food either. In a shop or a market stall and want something that you're not sure of the word for, just ask for uno così.
Buona giornata amici. (= Have a good day friends!)
