Ive gone three times in one week if that gives you any idea of how this review is going to go...
Ginza is my go-to sushi spot downtown. Good priced lunch specials (3 rolls +soup) for $11.95, excellent avocado & shrimp w/mayo dressing salad appetizer, and swift service. their spicy tuna rolls are my favorite in cleveland! also, the hot towel pre-meal is a nice bonus.
Not much i can say besides that I would recommend it above any other downtown spot. the best priced, fastest and best tasting sushi for all of us that work downtown and only have an hour for lunch.
Happy Hour (starts at 6 mon-thurs, 5:30 fri & sat) is 15% off of food and drinks.
Oh- and if you plan on sitting in one of the cozy underground floor tables.... plan on taking your shoes off!
