Anyone know approx cab cost in London?

[sweetheart]

Does anyone have an idea of how much it would cost to go from Oxford Circus to Westminster pier / waterloo in a black cab? Also, how many people can you fit into a london black cab?

We went by cab recently with 4 people, 5 is also still possible.

I think you need to think about £15 plus tip depending on how fast it goes. The meter goes by time not the distance. And the area can be clogged up at certain times of the day.

Depends on time of day.£15 sounds expensive to me for that trip. I would say under £10 unless traffic is bad of late at night.
