London
Mostly 6 decks, but some 4 deck games. Good pen (over 80%) depending on dealer and casino. Bad rules though, large spread required. Usually no heat!
Good casinos;
Palm Beach - classy & 4 deck
Park Towers - 4 deck and quiet, good for heads up.
Hard Rock - one 4 deck shoe, the rest are 4 deck CSM's, nice rock music atmosphere.
Cromwell Mint - 4 deck upstairs
Sportsman - 4 deck
Napoleons - 4 deck, but crowded.
Bad casinos
Any Gala casino - bad pen (60%)
Probably a good idea to fax ahead for membership, thus avoiding the 24 hours cooling off period.......
