Mary-Kate and Ashley Olsen headed to Las Vegas for a friend’s bachelorette bash that started with dinner – and ended in the club. The ladies shared a feast at Yellowtail Japanese Restaurant & Lounge inside the Bellagio, where they dined on signature dishes – such as Big Eye tuna pizza – prepared specially by the restaurant’s executive chef. After dinner, they headed to Gold Boutique Nightclub & Lounge – celebrating in true Sin City style. According to an onlooker, they were requesting songs from the deejay, and sang and danced along.
