The Venetian Poker Room is the best and (I believe) the largest poker room in Las Vegas.
The dealers are fast and fun to talk to.
There are plenty of games going on throughout the day.
They serve Fiji water and red bull for free.
Food service gets their food from the Grand Lux Cafe.
Comps and low rake... what else do you need? :)
When I'm in LV, I always stop by here!
