Calamari is one of my favorite dishes. I love deep fried calamari with a side of sauce. My fiance's work has a calamari dish with house sauce, which changes every day or so. It's phenomenal!
When it comes to what kind of beer I pair with calamari- honestly, I never thought about it. I usually drink anything with calamari. I really enjoy a nice IPA. It doesn't hurt to try pairing an IPA with just about anything. Personally, I think that the average answer would be a light beer. Lighter beers just "sound" better paired with something like calamari.
