I had the worst experience!!! I arrived with 4 friends and least to say the portions were very small despite our server reassuring us that the portions are big. I ordered a curry dish with the rice being 3 table s****s big and 1/4 of the very small pot was fulled with butter chicken. I asked the manager if i could change my order and he agreed. As he left my server came back yelling at me how im going to get him fired and caused a scene. Me and all 4 my guests stood up while we were getting yelled at! The manager came and told him to apologize immediately. Is this how you treat your customers??? The people who pay you? Horrible horrible experience. I will never go back!!
