I came here with a group of friends. We had made a reservation but still had to wait an hour for a table. If we had not made reservations, the wait would have been 4.5 hours instead.
For food, customers go out to get whatever sides they want and then come back. Once seated, servers will come around with meats and ask what you want. What I really didn't like about this was that the servers only had small skewers of meat and would almost never be able to serve a chunk of meat to each person at my table. It was not the huge meat eating experience I was expecting. Once you've tried a number of items, servers will ask what you want to come by but this is a lie. They are unlikely to actually bring what you want to the table. On the bright side, the food here is great. My favourite would have to be the cinnamon pineapple.
During the dining experience, Copacabana will have the occasional dancers coming around as well as a performer on the Chinese silks. This was a great distraction from my hunger when waiting for more meat.
