This is my go to sushi place in the Annex. Yes there is always a wait, so be prepared to stand at the entrance for a few minutes (15-30). Fear not, because it is totally worth it.
The Ikayaki is my 5 dollar (crazy good value!) late night staple, and the sashimi bronze combo (when I'm feeling splurgy) for every other occasion. Even just getting a single roll will fill you for under 10 dollars because each one has eight pieces. Everyone gets free soup and tea after being seated. Just the thing to warm you up!
The sushi quality here, and some people fight me on this (I'll reluctantly admit) is FANTASTIC. I only really eat sashimi, so it is important to me that the pieces are cut thickly/generously, and they are presented beautifully! Clean and fresh--give it a whirl. 10/10!
