Looks to be the same process one sees in high end Brazilian restaurants. Continuous cooking and slicing, as the carts/grills make repeated rounds of all tables delivering 7 or 8 different kinds of meat (beef, lamb, goat, bison, pork, etc). Pork should be fine if it's sourced from confined feeding facilities. Probably not smart to serve up a wild hog or bear. One can eat till he barfs, and he should not be prone to heart burn as it's usually a fat and protein overload. Usually expensive, but a great experience.
Sadly, it seems only the largest of cities are capable of supporting such an endeavor.
Have seen a similar cooking method used with Steamship Rounds in some Mexican markets as well.
Tough part at home would be the cook never has a chance to sit back and enjoy his work.
Looks very similar to an Italian bbq sauce I get locally. Same bottle different label as well. Probably comes from same Norcal food processor. Stuff I get though aint $20 a bottle.
I’d bet any good sauce or rub would be good on it though.
That would be my guess. Salt and pepper, and whatever sauce you like over a screaming hot grill that will burn your face off. In the video, he used briquettes but I'd try lump.
I like my steaks with a good sear on both sides, and red in the middle. The flip flop sounds really good for thick pieces of meat.
