just wondering how much it would cost for a cab ride from liverpool station, not really keen on the underground, anyone roughly know?

I would assume about £15.......depending on the time of day....because it's going through the city, traffic is pretty bad most of the day....You could get a bus, I believe the 205 goes from Liverpool Street to Great Portland Street....Why don't you want to take the Tube?? It's one train straight there....

Ive only been on the tube once and since im not keen on crowds it freaked me out abit, mind you this was at rush hour, bills great idea to get on at 5pm, it was sooo packed. But yea i think i will pluck up the courage and use that.
Thanx for reply.

I went on the tube - but that wasn't the difficult bit. its back a few streets and I had difficulty finding it, so if your not keen on the tube, I would definitely go by taxi!
