Okay so now I'd like to mention the Jester's buffet in more detail. I have started a list for others who like buffets (so please tell me of ones I've missed).
Anyways, this one does a breakfast buffet, a lunch buffet, and a dinner buffet at different times of the day (check http://elbowrivercasino.com/dining/ for details).
Rob & I are mostly there for the breakfast buffet on weekends, though I'm pretty sure their other buffets are nice, too.
The customer service is reasonable :) The food offers an interesting variety, including cereal and milk for the breakfast one, so it's not all "bacon & eggs".
There are other dining options there as well, which you'll see on the website link above. Hope you win big after eating ;)
