I have always enjoyed the food at Zipps but the last time I ate there the quality seemed less than usual. The burger was not as fresh, the onion rings tasted like they had been sitting for a while. Soda was flat, had to ask for a new cup and they did get me a better soda, but just another indication that things are slipping.
What I do like there is the Black and Blue burger with one patty, two patties and I am just stuffed. My wife really likes the Monaco wrap. Other than this last experience, the food across the menu is generally very good.
