Not sure if fish counts as meat, but I love a tuna steak, singed on the outside and basically, sashimi in the middle.
Otherwise, sirloin steak - to my mind, is the tastiest cut.
Funny thing, I notice that not one person has chosen veal... it is interesting to me how few omnivores have an issue eating lamb (effectively a young sheep) but many don't like the idea of eating veal (possibly those huge baby cow eyes evoke more emotion)?
