(In terms of those that don't require membership) The Hippodrome is one of the 'better' casinos in London. It attracts a varied crowd.

Best points are: There are mobile phone charging blocks - yay. There is also a restaurant lounge that is usually nice and quiet past 1am (perfect for a meal after a ...night. They serve food throughout the night up to the morning, I believe. Varied menu, too. The bathrooms are nice.

The doormen are strict. Though, they need to be. The casino is surrounded by multiple clubs, so you can never be too careful I guess.
