Can't get better ten-don and gindara saikyou yaki anywhere else. Even the special "ten-sei ten-don" at the 1 michelin * tempura restaurant nearby did not rival the ten-don here at shirou - I think I'd give it 3 stars on behalf of the michelin guide (that no one really cares about here in tokyo)
The "kodawari" of this restaurant is that the chef himself looks for ingredients at the tsukiji market himself every single morning for the freshest fish to work his magic with. Shirou make their tempura batter extremely thin & crispy, and their gorgeous ama-guchi sauce gives just the right flavour to the don as a whole. The rice served here is perfectly pearl-like and each tempura vegetable in the don taste so fresh that you'd think they chucked it in the deep frier a second after being picked out of soil.
ARGH nevermind you won't understand exactly what I'm trying to say unless you try it!
My previous favourite "Yamanoue" restaurant offers ten-don as well, for more than double the price - but recently I've found the batter a bit too soggy. Shirou revived my faith in the glorious TEN-DON.
