I love this place. I always go to the barbacoa restauarnt near the Omotesando crossing. I prefer the buffet which is around 4,000 yen all you can eat. Tons of amazingly delicious meats, grilled pineapple and a delectable salad bar. The food is amazing and the one other thing that sits well with me is the fact that most of the waiters are Brazilian. That gives a feeling of authenticity and supports the foreign community in Japan as well, something the government here does not do. I would highly recommend Barbacoa. Fantastic food.
