I have played at Bellagio through 3 WPT events (held at the Bellagio), and played $10/20 NL with a little $25/50 NL inbetween each time. The 10/20 was always spectacular until you reached the main game, and then it was still OK. I only sat 25/50 when I saw some fish sit in, which was like twice. I also played 15/30 and 30/60 limit, both great games. I am assuming everything below these stakes are good as well.
