London, UK; Colombo, Sri lanka & Cairo, Egypt

I will be visiting these places in Dec approx 5 days each. Any/All advice will be appreciated. I play Hi-Lo (Wonging if possible). What I need is where to play? Addresses if you have any-how to get there etc. Rules, Table min-max (currency), and most importantly pen and heat? Will try to give a report after returning. Thanks for any help. (I have played most casinos in the US, Canada, France, Monte Carlo, Macao & Sri Lanka when it was good! and have done well)
