Which Bar?

Trying to find somewhere to go for my birthday, I want somewhere mysterious and dark and sexy with nooks and rooms and cocktails. I've narrowed it down to three possibilities- Bond, Arthurs or Baroq. Does anyone out there know which is the best? Here's some pics to jog your memory:
Thats Bond. Here's Arthurs:
Couldnt get a pic of Baroq but their function man has sent me some very nice emails and I can apparently pop round there to have a look-see at their rooms- but what if only 5 people show up to my birthday? I'll feel really silly if we have a huge room all to ourselves and theres only a few of us there.

I also need dress-code theme ideas. It has to be magnificent, and stylish. In keeping with the style of the bar, obviously.
