How much is it for everything?
QUAN-t'è — contraction of 'quanto è'. The apostrophe elides the 'o'.
At the end of a bar session when settling the tab — asking for the total of all drinks consumed.
'Quant'è per tutto' = how much is it for everything. A very natural, casual way to ask for the total bill at a bar. In Italian bars you often pay at the end rather than per round.
Quanto viene con tutti i drink?
How much does it come to with all the drinks?
'Viene' (comes to) is the spoken alternative to 'è' for prices
Facciamo il totale.
Let's do the total.
Proactive — you are ready to pay and want to calculate the bill
Pago io per tutti.
I'll pay for everyone.
Treating the group — a generous Italian gesture
Paying in rounds ('a turno') is less common in Italy than in Britain or Ireland. Italians at bars typically order when they want, and at the end one person pays the full amount for the group ('paga uno solo'). The expectation is that next time someone else pays — a system built on social trust.
