More like 4.5 stars.
Went for lunch and stayed for dinner, as per my usual Vegas trick that I've learned from my fellow yelpers. Didn't really need to stay for dinner though, because the lunch on its own was quite impressive. Just about everything I tried ranged from above average to delicious, with more towards the latter. I was a little disappointed that there weren't any of the unique carving stations I've read on other reviews, like Ostrich or Kobe beef (maybe cause it was a weekday). But there were plenty of other great offerings. There were some good desserts, although I would have preferred seeing the ice cream and crepe stations from the Wynn. Service was very good too.. never had to wait for a refill. All in all, a great value for $20 for lunch, especially if you time it right with dinner.
