Since Jim 'N Nick's opened a few years ago, I have eaten there about 4 times. The first 3 visits I enjoyed the food. I usually get the Hickory-grilled Chicken Sandwich. It was always filled with a generous portion of white-meat (as per the menu) on two slices of thick sourdough grilled bread.
The last time I went there, I ordered the chicken quesadilla and the usual chicken sandwich. What a complete 180 degree turnaround in quality! The quesadilla had all dark meat and was skimpy on the portion (not to mention it was tasteless) and the sandwich was horrible. It was a combination of white and dark meat that barely covered the bread. And talk about the bread, it was two slices of thinly-sliced sourdough toast. What little chicken was in the sandwich was falling out because the toast was falling apart.
I never experienced such a turnaround in food quality at a restaurant ever. Some people might say I just went on a bad night, but the complete 180 turn was enough for me to NEVER to go back.
