Overpacked, tourists price, most tables taken by people not eating while those with food cannot seat (really eating occupancy rate way below 50% on that day, on our table of 20, only 3 - three- were eating while all others blocking places for nothing), how do you say stupid in Portuguese ? Definitely not a place for "brains". Avoid my all means.
