Not the some times poor service or most of their food, but they had a bourbon chicken skillet thing I really liked. Seems to be only 3 Denny's left in the OKC area and now their menu does not list it. Luckily I found a copycat recipe and will be trying to make a littler diabetic friendly version. Tastebuds can not wait.
