Sushi 86 is definitely a gem of a restaurant in downtown Cleveland. Some of the tastiest suhsi I've ever had, let alone in Ohio - ask for the kraken roll if you get the chance. It's not on the menu but comes with a delicious layer of squid salad on the roll which is to die for.
And to top off the good food, the place is a BYOB - so you get to save on the drinks!
Only thing keeping it from a 5 stars IMO are the restaurant hours - not open on weekends! :(
Try the bi-weekly sushi class ($50 for pretty much all you can eat sushi) for a great time and fantastic sushi!
