Cardroom of the size of Fortune which offers more tournaments then the latter. These tournaments are very fun 15-min level tubros, and they also have a monthly deepstack event (250 BB 30 min levels buy in for $235). Decent rake ( lower than in Tulalip, Fortune or Muckleshoot, higher than in Caribbean).
The same players come and play every weekend, but, unlike Muckleshoot and Fortune, they do not collude with each other against new players, hence the games are filled with action and excitement. Despite not being a regular, I made it to the final table 30% of the time I played there. Fields are smaller, too ( an evening tourney on a weekend will have 30-50 entries).
Cash games attract all types of players, most of them can be categorized by a phrase "degenerate gamblers." Players will call your pre-flop 3-bets with JTo, 22, 67o, A6o, will call up to the river, and will often get lucky. Because there is only 1 or max 2 1/3 NLH tables ( even on weekends) I did not play much cash at Red Dragon. Fortune, a competing cardroom located in the south of greater Seattle with 6-10 NLH tables running at any time, cannot be beat by Dragon.
Finally, floor management is very disorganized. Tournaments never start on time, floor manager can't decide where (lower or upper level) the tournament is going to take place, staff can't have the tournament clock start running, when chip up happens, floor manager forgets to stop the clock, dealers shout at each other in Tagalog while insisting that players at the table should only speak English: little details like these paint a greater picture of unprofessionalism.
Conclusion: it's a OK place to play poker in Seattle, but do not have high expectations of professionalism, organization, ambience or choice of games. Ethical players who do not collude.
