we just returned from 8 days in London. It's a great city with one negative issue. When traveling around the city, try as much as possible to take the underground trains rather than the black cabs. One they are very expensive and overpriced and two the drivers find it to be a sport to try and rip the tourist off by driving all over the place to get you to your destination.. I know London well and so I was aware of what each driver was trying to pull off. It's pretty aggravating to be made a sucker. It didn't work with me, but, still each driver became abusive when confronted with their tricks. In short, take the underground and avoid the hassle of being ripped off by the obnoxious and sneaky taxi drivers of London!!
