To me, fried calamari is a pretty simple dish to execute and tough to screw up
gotta disagree. simple stuff is often the easiest to screw up; case in point, fried calamari. far too often, it's tough, rubberbandy, or the breading doesn't adhere, or it's too greasy, or they slice the rings too thin and they cook too quickly. I've had more bad versions than good.
The one at Trattoria Demi in Evanston is pretty darn good. They toss it with sliced banana peppers and serve it with lemon wedges and marinara. Nice, big, meaty pieces of calamari, and they are careful not to overcook it. I also like the one at Davis Street Fishmarket where they toss it with a sweet/spicy asian sauce. When I worked at Carlucci in Rosemont, I ate our fried calamari every day. Nothing crazy, just a light breading (rice flour is the key), good quality calamari, and lemon/marinara. Haven't eaten there in forever, so not sure how it's stood up to the test of time.
