It never fails. Every weekend night, a crush of clubgoers invade Scottsdale's bar-heavy entertainment district by the thousands to drink, dance, and debauch. Typically, the destination for this roving horde of 21-to-35 party monsters is the intersection of Saddlebag Trail and Indian Plaza. This T-shaped crossroads is a nightlife epicenter of the Valley: There are a dozen hotspots within stumbling distance of each other, each with its own vibe, DJ selection, and amenities. Along Indian Plaza, there's a posh nightclub (Pretty Please) next to a beer garden (Bottled Blonde) next to a tequila-and-tacos joint (Casa Amigos) topped with a boutique bowling alley (Skylanes) across from a pool party haven (Maya). Over on Saddlebag Trail, hip-hop hub INTL, country bar Dierks Bentley's Whiskey Row, and open-air dance club Hi-Fi compete for attention spans. The scene is chaotic, bordering on shitshow territory, and Scottsdale Police usually block off both streets to traffic, so forget about rolling up in your ride. Stick with those speedy golf carts instead to get you to and from the madness.
