Freshness is guaranteed when you order this dish at Botan because the chefs only prepare it when they receive a fresh delivery of tuna. Which is only twice a week, and which also means there's a limited quantity to these beautiful bowls of tuna belly tastiness.
The reasons why this is so darn good is firstly, due to the obvious freshness of the fish. Secondly, the fat in the tuna belly produces a wonderful creamy texture after being minced. Last but not least, there's the blanket of tobiko, the single raw yolk and the crunchy spring onions, which you're suppose to mix together with the tuna and rice underneath. This begets a very sensuous and totally satisfying gastronomic experience.
