There is a fish store called "Tashiro Sengyo-ten" at the intersection where Imazumi Seven is located. It is a very ordinary fish store, but every Thursday, they sell limited sushi. It starts at 11:00 and they only have 40 servings. Whenever I pass by around noon, the sign saying "sold out" is usually displayed. So, I was curious and decided to try it once. I visited the store around 11:35 and managed to get one of the two remaining packs! It cost 550 yen. The sushi rice had a nice vinegar flavor and a homemade touch. The wasabi seemed to be a bit on the generous side, but it didn't bother me much. Since I was at work, I had to pour soy sauce over it. Well, I don't need to go out of my way to buy it again, but I'm glad I got to try this elusive sushi.
