Why is Bellagio so famous?

Could you elaborate on the reasons behind Bellagio's immense popularity? Is it due to its luxurious accommodations, world-class entertainment, or perhaps its stunning architecture and landscaping? What sets it apart from other resorts in the area, and how does it manage to attract such a diverse and high-end clientele? I'm genuinely curious to understand the factors that contribute to Bellagio's fame and reputation.
