I've been here couple of times. I love their meat, but i'm not so much a fan of their salad bar (compared to others, I guess). Food overall is good (thus the two stars), but I'm not rating that for now.
Last time I was there, the waiters were very unprofessional. Perhaps, it was not a busy day, but i thought that staying together in one area as a group--chatting, gossiping, I really don't care what they are discussing about--in front of guests is not appropriate in a place as fancy as this. I mean, they were just there, talking, not minding their customers. To be honest, I felt uncomfortable asking my waiter anything because it felt like I was interrupting their conversation. They didn't come back to check if the customers needed anything, except if they were actually called on. It was not a good experience for me (and the people I was with) even if the food and ambiance were great, and it was upsetting that we paid a lot to have service as such. Bottom line: not coming back again (unless if someone's paying). Anyways, there are other Brazilian places in town that I haven't tried so maybe it's time to explore some place else.
