Added: the chef is the worst part of this experience, he just hiding behind the staff and let the staff to face this situation. The staff keeps answering: sorry I have no idea of the beef, but the chef said the beef is the same. This meal is totally a disaster. These two pieces of meat are from mine and my brother’s order. We ordered actually the same part of the beef. But you can obviously tell the difference of these two pieces, the left one is much more tender and the right texture is really coarse. When we ask for the explanation, the staff just keep answering oh they are the same, what do you want me to do? I can’t believe this should be the quality of this level of restaurant. Also the waitress made lots of mistakes. In the beginning, we ordered two sets of meal, but they serve us only one set. I’ll strongly recommend not to have a meal on this restaurant.
