And as for the Topic of the Day...
I tend to like it all, and I do have to say that once you had some premium-grade, top-of-the-line, properly prepared sushi, there really is no going back. Well, yes, you can go "back", but there really is nothing like truly fresh fish (raw or cooked for that matter).
I also like eel (unagi) which is traditionally served cooked, lightly broiled. As for the raw stuff, I'm partial to tuna: toro and otoro (fatty tuna) and hamachi (yellowtail). I also like the tofu skins that are stuffed with seasoned rice, inarizushi.
