Having just moved to the area we weren't too sure which grocery stores to shop - or where they were - we tried some in Foster City - and 2 others in San Mateo - but made an easy choice sticking with Key Market. Nice- upscale little store with friendly employees who have helped me many times. They have a great little deli in the store - and I have ordered many party trays through them and have always been pleased.
If there is something that I don't see - they will order it in for you.
I would highly recommend this grocery.
