I haven't had "bad" sushi in a long time but one that REALLY sticks out in the past couple years goes to... *drumroll please*
Ichiban-YA on Thurlow (across from Joe Fortes) And from the looks of these other reviews (wrote mine on April 8) it ain't doing so hot!
This place seriously was my ALL TIME fave jap resto when I was a kid (previously named Ichiban-kan). I'd say from 2000-2005, I was there every weekend with my family. Local celebs LOVED coming here and waits would always be 30minutes+ to an hour. Best sushi of my life and the bonus was it was owned and ran by a Japanese guy!! After he sold it the new owner turned it into a small izakaya but prices were steep so we stopped going.
Fast forward 2011, I gave it another go cause I had SUCH good memories but it was a major let down. MAJOR. It was so bad I wanted to cry when I had to pay because I couldn't believe I was paying for shit. ARGH. It still makes my blood boil when I think how bad it was.
