Uber is uber-cool! Never had a bad experience yet. They're fast, friendly and you can track where they are in picking you up on their cool app. And if you want a bit more room when traveling with friends, simply select the SUV option. They also have promo codes they will send out occasionally for discounts. We used one last night for $10 off of our $18 fare. Awesome!! I also learned that not only do you get to rate the driver after each trip, the driver also rates the rider(s). Apparently I'm a 5 out of 5 stars (of course I am!). But if you treat the driver like crap or end up leaving a mess in the car, the driver can rate you low and Uber drivers can see your ratings and pass on picking you up. So be kind and keep that in mind!
Used to always use discount cab, but I've made the switch to Uber after the great experience with them (and after way too many stinky, gross cabs/drivers)!
