By far, one of the best cab companies I've taken National Taxi Cab will take you where you need to go FAST and SAFELY.
Not only that, they're on time, which I rarely am, so it's never a problem if they have to wait a few mins or 10, without the meter running! [Please never change that policy--customers will love you and keep coming back!]
I've tried to take other cabs in Fremont and they just don't compare. And what I found out was they actually pick up the slack when other companies can't do the job (I guess that's why it seems like they go by other cab names). My suggestion, call them direct at 510-651-7777 and you won't be disappointed!
