I would like to expand on what bansheeracer said, for the sake of completeness. This information comes from personal experience with the three Detroit casinos, and information found at
http://www.casinowindsor.com for Windsor.Casino Windsor's poker room opened on February 11, and is open 24 hours a day. I have not yet been there, but according to information on their website, they have a total of ten tables, spreading stud, Hold 'em, and Omaha. Limits start at 3/6 for Hold 'em, up to no limit. No information on Omaha or stud limits. I know nothing about their comp system.Motor City Casino's poker room has eight tables, also open 24 hours. The same three games are offered as at Windsor. Hold 'em starts at 5/10 going up to 20/40, with a $100-min no limit game, blinds of 5 and 5. The Omaha game offered is 8/b high low, 5/10, with a full kill. From 8am to 4pm on weekdays, Motor City runs what they call "Turbo" tournaments. These are $100 buy in single table tournaments with an 800/200 payout structure. Players start with T2000 and blinds start at 20-40, but I do not know the blind round structure. Different buy-in amounts are slated to be added, perhaps as low as $25 or as high as $1000. As mentioned previously, comps are available and free: self-serve drinks, chips, and cookies, and pre-made sandwiches for the asking. There is usually a waitress taking drink orders as well. Note that Motor City Casino's poker room is completely smoke-free.Greektown Casino holds the city's first poker room. It has expanded to 16 tables from the original 8 and is open 24 hours. Games spread regularly are stud and Hold 'em. Stud is offered in 1-5 or 2-10, and Hold 'em in several flavors: 3/6 up to 20/40, and two no-limit structures: $50 min, $100 max with blinds of 1 and 2, and a $100 min, no-max game with blinds of 2, 5, and 5. Friday is the home of the big game, a $1000 minimum buy-in no limit game, blinds of 10 and 25. Finally, Tuesdays at noon a pot-limit Omaha game, high-only, is spread. I don't know the min or max buy-in, but I believe the blinds in that game are 5 and 5. The floorpersons handle comps, which for the lower limits are a $6 coupon to (essentially) a hot dog stand just outside the poker room. For the higher limit games, I would imagine full comps to one of the nearby restaurants are provided. A full bar is found in the poker room, with at least one waitress taking orders at all times. Greektown Casino's poker room allows smoking on the lower limit side, save the 1 and 10 seats at each table. No smoking is permitted in the higher-stakes room.The MGM Grand does not yet offer a poker room.Whew -- hope this helps out those in the Detroit / Toledo area who've always wanted to take the B&M plunge.Edited to add information about smoking policies.
