The tuna belly is perfectly sliced, with a tinge of sweetness. As you chew on the tuna slice, close your eyes, appreciate it gradually dissolving in your mouth, sliding to the back of your throat. Close your eyes, the $5-a-piece tuna belly slice is now in your stomach. Yummy, as you showed off a huge grin on your face.
Oh I digressed. The wasabi pairs really well with the tuna belly. Strongly suspect that the wasabi is the real deal (i.e. Not horseradish; can someone verify?). The rice was really tasty, its temperature was perfect. Highly recommended!
