As bad for me as fried zucchini has to be this stuff from Ted's Burgers in Anaheim is some of the best I've ever had. It keeps it's crunch for hours and goes well with blue cheese.
It's a little salty but then most diner food is rather salty. I will get this again.
When you grab your zucchini and the breading falls off that is not a good sign. Past that I found this California Grill & Bar Zucchini Parmesan passable, not great, but passable.
