cabs run on meter, insist that they do, do not quote any price, just say the destination and hop on, then whatever the meter reading is double it up and add Rs.2 . that is the price u pay, and Dipyaman, in Kolkata bhojohori and 6 BP charge almost the same, I know in Blore 6 BP is audaciously high charged place. And being in SL, he will find it easier, anyhow if U have only a day, have a good time at park street.
