I've only been once, recently. I wrote a review of it on the pokerwikki page AKQJ10 contributes to. I've lost my link to the site, or I'd give it to you, but you should be able to find a link by searching the archives. My review was pretty thorough; that's why I mention it.
I went on a Friday night--got there about 8ish to avoid a wait, but there really wasn't much of a wait for any table all night (except the no limit hold'em table--30-45 minutes).
There's some construction to the roads, but you can still find the signs with their directions. Check out their site:
potawatomi for directions.
I stayed till about 1am. Around 11:30pm what I assumed were fish (young guns in cowboy hats--in
Wisconsin! [img]/images/graemlins/grin.gif[/img] ) started arriving. I wish I would have stayed, but my partner had cashed out.
You will find a phone number on the site to call to see what games are playing and about the wait, etc.
