If I was looking for a small limit poker game in Vegas, the Bellagio would be my last choice and the Wynn a close second. The Bellagio looks down their nose at 4/8.
You'll find a friendly game for small stakes hold'em at Monte Carlo and for a little more action at the MGM. Some of the lesser casinos offer small stakes hold'em, but I haven't played there.
While I love staying at the Bellagio, I really didn't like the treatment in their poker room.
