We tried Hakkasan because of the many good reviews. The food was as good as advertised from a flavor perspective and the atmosphere was nice but that is where the good part of the meal ended. The portions were microscopic despite our waiter cautioning us about the large portions to share before ordering (which is why we didn't order any additional small plates). Portions were so small that my wife and I both needed to get something to eat immediately after finishing dinner!!
Service was average (polite but unexceptional) and pricing was ridiculously high for what you got - even by Vegas standards. Would definitely not return or recommend. Big disappointment. You know it was not a good experience when I purposely waited a day to write a review and felt even more ripped off today than I did yesterday.
