The best ticket agency in London with the friendliest staff

Been using this ticket agency for years and they've always offered the cheapest prices for tickets. There have been a couple of times where I've booked tickets in error and they've always cancelled them for me there and then; other ticket agencies are reluctant to do so unless you've paid extra for their insurance scheme.
There have also been times where the agency has had tickets that have sold out everywhere else :)

So glad they exist.
