Hi. Just to try and answer a few questions. I lived in Brasil for over 10 years, and the "Churrascaria" is the barbecue system that they use of marinating the meats for sometimes several days,(often in a paper wrap to keep the moisture in), and then rolling them in salts and seasonings and grilling them over a wood charcoal fire. "Rodizio" is the serving method of the waiters coming around to the tables with skewers of meats to carve off the exact piece that "tickles your fancy" at that moment.
My husband and I love them so much that we have made it, almost, a quest to find as many that are here in the U. S. as is possible on our budget. In our opinion, the two best ones (so far) are in Dallas. They are Boi Na Braza, and Fogo de Chao. We have not been to Plataforma in NY yet, but can't wait! We were just in the L.A. area and found out that there are about 11 there now, the best in our opinionn being the "Amazonas". There was also a pretty good one in Redondo Beach on the water. Very romantic! We are next headed to two in Chicago, called, again "Fogo De Chao" and "Sal e Carvao". There is even one in Phoenix but it is not too large. There is also a reasonably priced one in Las Vegas. (Or there was about 4 years ago). Orlando has one too that just opened called something like "Crazy Charlies". Wasn't too bad at all.
In most of the Brazilian ones, the only organ meats are chicken hearts and we definitely did develope a taste for them, they are highly seasoned bits of a flavor burst. There is, also, a good "Churrascaria" in Boston, even with a Brazilian guitarist and smooth music to sooth that ever expanding "tummy".
We just went back to Brazil for a visit and they still have the very best ones of all, and the whole meal was for the grand price of about $10.00.
If you go to one of these, do yourself a favor and have the national drink called a "caipirinha" (ki-peer-een-ya). It is a lemon-lime ground with a mortar and pestal and then alot of sugar is added, and ice and any liquor that you like. The most popular ones are with vodka or rum. Yummmmm! :)
Here's to a great time...."saude" (sah-oo-gee, Brazilian for to your health.)
