I quite enjoyed my experience at Roll N Bowl. It's located at the southeast corner of Midland and Ellesmere. It's more expensive than Ni Ji across the road but I liked it way more as you can see from my review of Ni Ji (though the fish there was pretty fresh).
I have a feeling this place is called Roll N Bowl because they sell rolls (Japanese food) and bowls (Korean food) as it is Korean-run. I believe meals come with soup and salad. Service was really friendly and the ladies who served us were going around giving free Korean side dishes to everyone as there was a bit of a wait for the food. I found that quite a considerate thing to do - and also good damage control as well as hangry customers are not happy ones!
We ordered takoyaki as a side dish first and it was all right - nothing amazing but not a bad snack. We ordered two rolls as well - a black dragon roll, a fantastic roll, and a rainbow dragon roll.
The fantastic roll has torched tuna, tomato, and garlic sauce which I think is quite unique though it didn't taste quite as fantastic as I thought it would be and the garlic sauce was not very distinct. I think the snow valley roll at Nichiban Sushi4U does it a bit better - they also have torched tuna with garlic sauce. The rainbow roll has torched fish on top unlike other places where it's raw and it was quite good! Everything tasted fresh - not much more to say.
Strangely enough I liked the black dragon roll the most - again the ingredients were very fresh. I think personally I don't like having too many sauces on my rolls which the other two rolls did have a lot of sauce ( I scraped it off). This roll comparatively is quite light though the portion is still really big! Even though these rolls are more expensive they don't skimp on portions which I think is nice.
Overall a good experience and if I'm in the area I'd be back again.
