After marinating some beef tenderloin with galangal herb, chef Richard Yu finishes off the succulent cut with a sweet-and-spicy cambogee sauce. This signature dish is emblematic of the China-born cook's creative work at Mosaic, where his Asian-fusion and American meals stand out with locally grown produce, hand-cut meats, and fresh seafood. He also puts his unique stamp on other classic Eastern and Western dishes, such as his orange chicken with sun-dried mandarin-orange peels and his 8-ounce salmon stuffed with crab, shrimp, and cheese.

To complement Chef Richard's cuisine, bartenders craft a variety of hand-shaken cocktails such as Mosaic's signature Mosaic-Tini, a blend of muddled strawberries, simple syrup, and organic riesling. Many of those cocktails come spiked with house-infused vodkas, and other imported liquors also stock the bar alongside wines and domestic and imported beers.

Meals unfold on Mosaic's outdoor plaza or in its chic lounge inside the historic Four Points by Sheraton San Jose Downtown hotel, which affords stunning views and often hosts late-night entertainment. A nightclub sets up residency Thursday–Saturday nights, and jazz musicians improvise their way through tunes in the dining room each Friday and Saturday.
