Someone calls him a bistrot, to feel a little Parisian, someone trattoria to give up his tie, another osteria or ristorante based on the emotional suggestion or the degree of formality of an appointment.
No matter what the definition of the 'Cavour' is. It's a bit of all this; the important thing is that the customers feel at ease, finding the intimacy of a romantic rendez vous at the table, a free chat for an evening aperitif at the buffet counter, the relaxing reflection of an after dinner in front of the fireplace.
A bit of all this or all of this together. In the same evening.
