I have used Ambassadors on City Road a few years ago, so I'm unsure on how relevant my experience was by today's standards, but I must say I didn't have a terrible experience. I handed over a small fee on the door and got let in at approx 4am. I then had the choice of around 5 WG's. None of them were top class but also far from the dregs.
Shower in each room to use before and after, pay for half an hour expect to get 15 to 20 minutes of actual interaction.
I guess what I'm saying is If you are looking for a quick in and out with shower facilities and 5/10 to 7/10 girls then it's cheap and close to the centre.
Like I said, I can't guarantee it is the same as when I went there but I didn't feel completely robbed considering I just turned up at 4am and it was quite a clean place from memory.
Unsure if there are others that are better/worse.
May be worth getting a second opinion from somebody who has been there more recently before banking on my experience a few years ago.
Have fun whatever you get up to!
