I've used Yellow Cab of Pittsburgh at least a dozen times to get to the airport and back and similar trips. It's easy to order a cab, they always show up reliably, you can pay by credit card, they give receipts, and basically do everything I expect from a professional taxi service. During the middle of the night they once showed up within 30 minutes, which is pretty good for PIttsburgh. Not immediate no, but in the US you only get immediate cabs in New York and Boston as far as I've experienced. I'm surprised at how unhappy other reviewers are with Yellow Cab - I have had different experiences.
Pros: Turn up on time, every time
Cons: Plan ahead, not immediate
