It costs roughly 52-55 dollars, I usually give 60 just as a tip. All the Taxis are good, I typically have liked the Black and White or the Yellow Checkered one, but keep in mind, the Yellow Taxis are more expensive for some reason. For your 4 am Taxi, you need to call them and make sure they will come on Time, and call them half an hour before and remind them as well, just incase they sleep on the job. Have Fun.
between 45 and 60 dollars, depending on the service you use
