We were joking that there's no way to make this dish look good, but thankfully it certainly tastes good! If you prefer heavier and fattier fish like in this case- tuna, this is definitely a great option. It was incredibly rich in taste because of all the fats, but nonetheless, very satisfying, much like eating a good slab of steak.
Do note that it got too rich after a while (and that is why they have thoughtfully complemented it with radish and lemon) so to get the best of both worlds, I'd recommend getting another lighter tasting fish to share them with a friend.
