Big Dog City was recommended to me by a friend when I needed a taxi to take to teh airport. I actually called the taxi service the day before and they sent the taxi right on time. The rates are pretty comparable to all the other bay area taxi companies. The driver was really friendly and helped me with my bags. He was a safe driver and did not speed too much. But I did like the overall service and convenience. I did not have to wait to long for the driver. Highly recommended.
