We just got back from Harrah's Chester. I had read on their facebook page that they redid the buffet. They eliminated theme nights (BBQ, Seafood, Prime Rib and Italian nights) and the price was now $19.99 every night ($15.99 for lunch). We decided to take a ride over for a few hours and I had a free buffet coupon so we went for lunch.
As I expected, a lower price also meant a lower quality experience. There are not as many choices as there used to be at the salad bar, entrees or dessert area. What used to be the carving station is now a nacho chip bar with a bunch of toppings. Quality of food was fine, not noticeably different than before. Just fewer choices and, I suppose, fewer higher end items.
I was curious if HET has done anything similar at the AC properties. I don't know why they did it in Chester. I'd rather pay an extra $2 or $3 and have it the way it was before. Perhaps they weren't getting enough business and felt a lower price would attract more people. Or maybe the theme nights weren't that popular. I know we didn't like the fact that the most expensive night was Saturday night for Prime Rib because neither of us eats red meat so we were paying extra for something we weren't using.
