Shall we have lunch together tomorrow?
'Pranziamo' = pran-ZIA-mo. 'Domani' = do-MA-ni.
Use this for a lunch plan — particularly in work or study contexts where lunch is a natural break. Lunch together is a daily Italian social ritual. In Italy, lunch ('pranzo') is still an important meal, not a rushed sandwich at a desk.
'Pranzare' (to have lunch) — 'pranziamo' is the first-person plural suggestion. 'Insieme' (together) is implicit in 'pranziamo' but can be added for emphasis. Note the difference between 'pranzo' (lunch noun) and 'pranzare' (to have lunch verb).

Establishing the lunch format and duration
Italian lunch culture varies by region and generation — in the south, a long midday meal at home is still common; in northern cities, lunch is more likely a quick break. However, the 'pausa pranzo' (lunch break) remains sacrosanct — typically an hour minimum. Going out to a trattoria with a colleague is an Italian daily social ritual.
