Important to clarify my method for reviews. I am a firm believer that each review is carried out on a relative scale. That is, I don't compare a buffet to one of Bobby Flay's restaurants.
Five of us visited Wicked Spoon and were very impressed. Good selection, great decor, nice variety and super service. One gripe was that the food was a little lukewarm. Seemed they were expecting their "normal" busy night and things were dead with the NCAA Tournament playing out during dinner time. If I was in Vegas and seeking a buffet (that pretty much always happens) I would not hesitate to pay another visit.
