Sushi Suzu, yes, I had lunch there last year, and dinner also. It wasn't so high in the Tabelog at that time. The lunch was actually more enjoyable than the dinner in my opinion. The dinner nigiris were a bit salty, the chef changed them to go along with drinks perhaps. But I preferred the lunch version at 5000 yens (10nigiris, one maki, miso soup).
The setting is actually very nice, in a counter in front of the chef, and on tatami. The chef is quite young and open - if you push him a bit (hihi!).
Aso, my recommendation is to not go for the full course, but just for a simple nigiris set, the price is reasonnable. And overall, I did not feel that this sushi was a revelation - especially for a local resident !!
