I mean, it's The Venetian. Say no more.
One of my very favorite casinos in Las Vegas! The interior is simply amazing, and they have a wide variety of games, from penny slots to Blackjack to Craps and Roulette. Despite the prevalence of people smoking indoors, I found The Venetian to be one of the cleaner, better smelling casinos in the city. The exterior is awe-inspiring and the indoor courtyard is just as majestic as anything in Caesar's Palace. Plus, it has some nostalgic value for me personally, as it was the very first place I ever won big ("big") at both slots and Blackjack.
