I just took a cab in Bristol twice. One was the day I arrived, the second time was the day I moved to Unite House. It's very very expensive of payment(at least for me,haha). Once u get on the cab, it will cost u 2.8 pounds, which equals ca.40 HKdollars. NB. just the begin payment~I can nearly use the same amount of money to see a movie in HK,, thus I prefer to see a movie rather than take a taxi
