fresh, delicious sushi!. first of all, mamakat (who wrote the review below) sends backfoodat every restaurant just because she doesn't like it. i eat there and speak to the owner all the time and can assure that the restaurant always receives fresh fish of the highest quality. the owner and staff are very friendly, and the sushi there is just amazing. with options that cater to everyone, including those who don't eat raw fish, are vegetarian, or can't consume gluten, they really do make the tastiest sushi in town. i've tried many sushi restaurants in ottawa, but nothing beats sushi umi! my favourites here are the tempura yam roll, dynamite roll, citrus roll and yummy roll - delicious!
