Graton Resort & Casino Celebrates Billion-Dollar Expansion with Star-Studded Gathering

Details of the Expansion Project

The $1 billion project added a new 28,000-square-foot smoke-free indoor-outdoor restaurant called AYA along with new slots, a sports bar, rooftop dining, and other features that increased capacity and variety for visitors. These additions opened to the public on May 4, 2026, and the May 8 celebration served as the formal recognition of the completed work. According to the San Francisco Standard, the upgrades focused on creating distinct spaces that combine gaming with dining and entertainment options in one location.

People familiar with the property note that the new slots joined the existing gaming floor while the sports bar and rooftop dining areas provide additional spots for guests to gather. The 28,000-square-foot AYA restaurant stands out because it operates as a smoke-free indoor-outdoor venue that accommodates different dining preferences throughout the day and evening hours.

The Celebration Event Unfolds

Mario Lopez served as emcee for the evening, guiding the program that included performances and remarks from attending guests. Carmen Electra, Hunter Pence, and E-40 joined the red-carpet arrivals while Lt. Gov. Eleni Kounalakis represented state officials at the gathering. The program featured dining options drawn from the new restaurant spaces plus live performances that continued into the night and generated media coverage from local and regional outlets.

Those who attended observed that the event highlighted the new amenities in action, allowing guests to sample the sports bar and rooftop dining areas during the celebration. Media representatives documented the arrivals and activities, which focused attention on the expansion's debut just days earlier.

Reports indicate the celebration aligned with standard practices for major resort openings in California, where properties often schedule a public-facing event shortly after initial operations begin. The presence of both entertainment figures and government officials reflected the dual role such expansions play in local economies and visitor attractions.

Key Attendees and Their Roles

Mario Lopez handled hosting duties that kept the program moving between speeches, performances, and dining segments. Carmen Electra and E-40 appeared as celebrity guests whose presence drew additional attention to the evening's activities. Hunter Pence, known for his baseball career, joined the group and participated in the red-carpet portion alongside the other notables. Lt. Gov. Eleni Kounalakis attended in an official capacity that underscored state-level interest in the project's completion.

Event organizers arranged the schedule so that attendees could move through the new facilities, including the AYA restaurant and the sports bar, while performances took place in designated areas. This structure allowed the celebration to showcase the expansion's features without interrupting regular operations that had started four days prior.

Context Within Regional Gaming Developments

The Graton expansion fits into broader patterns of investment seen across California gaming properties, where operators have pursued upgrades to attract both local and out-of-area visitors. Data from industry sources shows that facilities in the Bay Area and Sonoma County continue to evolve their offerings in response to changing guest expectations around integrated dining and entertainment spaces.

According to coverage from the San Francisco Standard, the May 8 event captured the moment when the $1 billion investment transitioned from construction to active use. The addition of new slots and the 28,000-square-foot AYA restaurant represents measurable increases in square footage dedicated to specific guest activities, while the sports bar and rooftop dining create layered options that extend the length of visitor stays.
