Casino M8trix, Gaming venue in San Jose, United States.

Casino M8trix is a cardroom and casino in San Jose, California, housed in a glass tower and offering several floors of card games including poker, blackjack, and baccarat. The building also contains a sports bar and a restaurant, making it a self-contained venue where visitors can eat, drink, and play under one roof.

The business began in 1946 as Garden City Billiards Parlor, founded in downtown San Jose by brothers Chris, Louis and Nicholas Dalis. In 1976 the family moved it to a chateau-like building in West San Jose and renamed it Garden City Casino. After a 1998 bankruptcy filing, it was sold in 2007 and reopened in 2012 as Casino M8trix.

The casino's name is a play on "matrix," with the 8 standing for the eight floors of the building. Its on-site restaurant, Sushi Confidential, opened in 2023 and serves a sushi roll named after the casino. The venue also supports charity programs such as Second Harvest Food Bank and the HERS Breast Cancer Foundation.

The casino is open around the clock, so there is no need to plan around opening hours when deciding when to visit. It is worth checking in advance which games or tournaments are running on a given day, as the schedule can vary.

The casino's roots go back to 1946, when three Dalis brothers opened Garden City Billiards Parlor in Downtown San Jose; in 1951 it became a Hofbrau with a "Bavarian Room" for dancing and music. The business moved to West San Jose in 1976 as Garden City Casino, and the M8trix name arrived in 2012.
