As his dinner came to a close, the restaurant presented Schwarzenegger with a two-tiered custom cake to celebrate the actor’s milestone birthday. The group paused for a moment to sing “Happy Birthday” to the star, as he made a wish and thanked his group for spending his special night out in Vegas with him. Ready to take his celebration to full party mode, the group made their way up to the fourth level of the complex and took a seat at their VIP table located on the main stage. Immediately getting the party started Schwarzenegger and his guests joined in a toast and began dancing to the beats of legendary DJ icon Tiësto.
