Do you have a car? If so, San Mateo across the bridge has plenty of Japanese. If you are craving high end sushi, Yoshizumi is near by.
Foster City has a large Hong Kong population, so there is a fair number of cafes serving HK food. I haven’t really explored it, but that’s something to consider.
If you like seafood, and you feel like cooking in your corporate housing, I heard Dragon Baby Seafood have a stand at the Foster City farmers market (I think on Saturdays). All manners of seafood catered to the Hong Kong population that are very infrequently, if at all, sighted at the Bay Area grocery stores- e.g. eastern coral trout @Night07 . We bought seafood from them via delivery. A few great hits and a few misses in terms of freshness. So being able to check out the goods live at the market will ensure freshness.
