Best I've had in the US was at Claddagh Irish Pub in Lyndhurst OH (Cleveland suburb). Luckily I was warned about the size of the portions and tried a half order. It was all I could eat. Now I can take of leave the chips, but the fish is outstanding. I've been there a half dozen times and never ordered anything else - although I started with potato bacon soup once and it kept me from finishing the fish. Light but substantial batter, crispy on the outside. Mild moist white fish on the inside, probably cod or pollock. Mmmmm. I'm making myself hungry.
