I've gotten Chicken Shack 3 times. The first 2 times were around lunch time, and I thought the food was amazing (I've only had the fingers and wings so far.) I LOVED the fries. The third time I went there was a Friday afternoon, and everything had less flavor, even the sauce. The fries were really soggy and seemed like they were undercooked as well.
I'll try again, though, and hopefully that one Friday was just a fluke.
