We have not stayed in the hotel or eaten in the upscale dining area.
We had the buffet dinner on Labor Day Monday. It was a very good meal, with an emphasis on BBQ that day ( including brisket, back ribs, pulled pork), plus the usual things like carved pork loin, fried and rotisserie chicken, various hot and cold salads, a pasta dish, a small selection of Chinese food, soup, salad bar, etc. Non alcoholic beverage was included, as was a large dessert bar.
All food was hot and we found many items we enjoyed. Weekday dinner price is currently $18 unless you have discounts of some kind. That day it was half price for Players Club members. They have a Senior breakfast buffet special on Monday and Wednesday mornings that is very reasonably priced and has a nice selection. Wait staff was friendly and efficient. Although I think the Davenport Casino has a larger selection of dishes in their Buffet, we have always found good food at Jumers.
This is a nice, large Casino complex: well maintained, smoke free, the large parking lot accommodates RVs or trucks, plus a covered parking area.
