We just moved to a new office in Millbrae, California. The move was only about a 1.5 miles (2.4km). The best part is that we are right across the road from the subway station (Millbrae Bay Area Rapid Transit station). I signed up for an EZ-Rider subway card that tops up automatically. It is so convenient. If you are in London or Tokyo it is like the Oyster and Suica cards.
If you are in the neighborhood, feel free to stop by and introduce yourself. We are at 10 Rollins Road - Suite 212A, Millbrae, California 94030
