I haven't eaten in the actual restaurant yet, but I've grabbed takeout 4 out of the last 5 nights.
Comparatively to other sushi places on Bloor, I'd argue Big Sushi has the greatest value in terms of quality of fish, generous portions while still be pretty cheap.
Favourites so far are, T2 take out special, spicy salmon tempura roll and the Chef's special Roll A.
This was a weak review. I'm sorry.
