Being FT RVers, we have visited quite a few small casino in the past 3 month so when we heard there was a small casino near our campground in Ft. Randall, we were not overly excited.  Most we visited were not worth the visit.  But, were we pleasantly surprised.
As you walk in the front door, notice the incredible mural over the hotel desk.  It is an incredible painting of Bison.  Really sets the tone for the casino.   It is a very clean casino, nicely decorated and personnel where visible making sure it stayed clean. 
Players Club personnel were friendly and the club has some very nice perks.  Great customer service skills.  They have $50.00 drawings on some evenings which is always fun.  Remaining personnel where also very nice and always there to answered questions.  Wednesday is Senior Day and worth going too.  
The slot machines are a combination of older favorites and new ones.  Not overly tight so you saw people winning and bonuses paying out nicely.  It was a really fun experience.
We went to the Monday night Prime Rib buffet and Wednesday night Steak Dinner.  Both were exceptional and portions were large.  They have a limited menu too on those night.  Your players club give something off I think so check into that.  Worth the trip for dinner.  Wait staff were friendly and very attentive.
All in all this was a really fun time for us.  We will definitely go back when we are in the neighborhood.
