OK I can clear up some poker related questions about these places you are mentioning.
Gala Russell Square does have both cash tables and tournament poker, see cut and paste below:
"Texas Hold’Em Cash games
Everyday, 20:00 hrs – Till late
£50-£500 sit-down dealer dealt cash game. Complimentary soft drinks and valet parking, smoking balcony next to the tables."
Gala Tottenham Court Road also has 1/1 holdem but no tourneys.
There is another place that is better than both those but im keeping it under my hat....or until ive at least had a few beers with you guys hahahaha..
