Yellow Cab is all over south beach and near the airports. It has to be one of the biggiest cab companies around here. Only bad thing is that most cabs arent usually very clean, AC doesnt work, and they make noise. Once I had to stop while the guy got gas! However, they are somewhat reliable in that they always come when you call them. Even though they are sometimes a little late. And the cabbies seem to know where they are going.
