According to the Wikipedia The Italian government claims there are 25 million Brazilians of Italian descent, which would be the largest population of Italian background outside of Italy itself.
Around some of our neighbourhoods you can see - and feel - Italy all around. It's present in the architecture, the accent, some of our vocabulary word and...the food! Ah the food. We have great Italian cantinas, restaurants and...pizzerias. I heard so many times that the Pizza in Sao Paulo it's the BEST you can find. I heard this even from some Italians who visited Brazil.
Living in London for nearly ten years, what I miss the most it's the food. London has amazing restaurants and all of that though...there's no FOOD like the one at home. And there's no Pizza like the one in Sao Paulo. Saturday night we went to Princi in Soho and...it was the first time I found a Pizza I could say it was a proper Italian - Paulistana - pizza. The sauce, the thin base with the chunky borders... Made by Italians, served by Italians...The environment at the Princi makes you feel like if you are in a pizzeria in Italy; it's noisy, loud, crowded and with proper Italian delights!
