The poker room is the largest in Deadwood but surprised if they ever see more than 2 tables cash. Maybe Fri/Sat nights. Room seemed well run but some different SD laws. No phones at the table, if you even pull it out someone can call you on it and you hand is dead, chips forfeit. Nothing like that happened but given the tournament seems like ripe opportunity for angle shooting.
No food at the table was an issue for tournament, given that and no dinner break for Day 1s it's an issue. Pack protein bars.
Worth checking out if your in the area but I wouldn't go out of your way.
