I originally wanted to go to Toji Sushi next door. This place only had one other review and no pictures, and tbh Toji had better decor and I wasn't gonna risk it.
However, I stood in Toji Sushi's door for a very long time and their staff was busy doing something indiscernible near the bar. Essentially, I was being ignored so I walked two shops over and went to Sushi Osaka.
I absolutely do not regret the choice.
The shop is super small and run by a very nice old lady. The furniture and decor may not be top notch, but it does the job.
The food is reasonably priced and their lunch menu having lots of variety.
I got the sushi lunch - 8 pieces of sushi and 6 California rolls. Comes with soup, salad, drink for $12.95.
Also it tasted delicious.
5 stars because the food was tasty and they really didn't do anything wrong at all. They just have the disadvantage of being beside a bigger, more known and funded Toji Sushi.
I'm sure either choice is good, but don't disregard Sushi Osaka just because it only has a couple reviews.
Great experience, would definitely come back :)
