I called around, and after talking to several companies, these guys were clearly the pros. The car was very nice (and clean!), the driver was on time, and the service was exceptional. And the rate was about the same as the other taxi companies I called. I'm not positive, but I think these guys might be the only ones with all the permits required...at least that's what it says on their website. Anyway, I plan to use NTAT again, for sure.
