Not sure why they would serve on a plate and not a bowl, as it does not look as presentable. I have also tried the Wagyu beef at the outlet in suntec, so I can compare this against that, and I have to say the suntec one beat this hands down.
However do try the sashimi or the kaisen don, it is really really good. The set also came with chawanmushi (not available in suntec outlet) and a matcha mochi.
