Most 2/5 games in town are good. It really depends on the day and time of year or specific venue going on (i.e. WSOP @ Rio or month of special tournaments at Palms). If you want to play some deep games with 2/5, then I suggest the only place in town, Wynn. Bellagio is $200 cap BTW, and you can earn higher rates per hour at most other 2/5 games in town.

As for $5/10, the only casino regulary spreading it is Wynn. It can be deep at times, good at times, bad at times. Usually if there is a must-move, the game will be good. On weekends, this game can get fantastic.

I know Palms and MGM will SOMETIMES spread $5/10. I only played in each once. The Palms was a chop fest (although I have heard it is normally good), and the MGM was amazing.

You can always sit in Bellagio $10/20 game short and give it one shot. Just don't let yourself go on tilt if you lose or put in an amount you can't afford to lose. This can also be a good game on weekends and sometimes during the week, especially during certain venues. Whenever there are tournaments for WPT or something in town, Bellagio 10/20 crawls with fish juice.

The best month for me in Vegas was back during March Madness when the WPT Championship @ Bellagio was in town. There were always 5-6 tables of must-must-...etc., -move games going and usually all, but the last one or two were GREAT. I lost the biggest pot of my life that month and have not won a pot close to that size and it was still the most profitable month I have had ever.
