ISO properly cooked tuna in restaurant
Friend of mine believes that the only good cooked tuna (when cooked in restaurants) is always of the sushi-grade, seared-outside-raw-in-the-middle variety. I remember having an amazing grilled piece of tuna when on travels in Italy and was hoping to find a restaurant that does similar justice to tuna and doesn't only do the raw-middle variety. I thought it would be easy to find, but haven't come across any recently. Any recommendations?
