On a late pass through Scarborough, I cracked open the Yelp app (who can live without it?) to get a lay of the land. Roll N Bowl was along my path, so I stopped in.
The place is small and cozy, and the food was good. I tried my usual test case of sushi and sashimi. The fish was fresh, with good texture. Prices are pretty nominal, so you really can't go wrong as far as I can tell.
It's on my list for next time I'm in the area. I'll probably go in a bit heavier and see how they do on the more complex meals.
