Let me start off by saying that if you are going to Copacabana Brazilian steakhouse, just go to their Adelaide location. The service is faster with a larger selection for not much more.
Despite this, the meats were amazing and waiters friendly and charming. I went there for a birthday dinner and my friends and I were all impressed with the selection of meats and the professionalism of the people serving them. The Brazilian dance performance was captivating and a cherry on top of a fantastic night.
The only real issue I had - albeit a large issue - was with our server. No friendliness, negative attitude, simply barked "do you want a drink" rather than politely asking. She would go up to 40 minutes at a time without checking on our table, then come over with a reluctant attitude as if serving six people was a huge burden. If you hate your job that much, maybe you should quit. Took us forever to get our bills because this girl was so slow.
Despite the unenthusiastic server my birthday dinner was great, would definitely recommend Copacabana for the food and atmosphere!
