The food is fine, but the service and the wait suck. They had a Portugese sausage that I remembered liking when I visited Portugal last year. That was fun. Otherwise, I guess I was reminded that I just don't care much about buffets anymore. They used to be a great value, and they were certainly easier to do when I was younger. Nowadays, I can take them or leave them.
As for the Wynn casino itself, it is seriously tacky, even for Vegas, and way over the top. My wife remarked that it was the kind of place that a 55 year old guy would take his 28 year old girlfriend after he bought her a boob job.
