I can't recommend enough the 4-8 game at Bellagio. It can be tight during the day but at night it's a great game. The rake can kill you lower than 4-8, plus it can be difficult to play straight at something so low. Most buy in for 100, but 200 is appropriate. It's hard to lose the whole thing. Plus, considering MGM is a long walk, upping your limit may be worth it. The 3-6 at Mirage can be fun as well and is a little closer than MGM.
