Spacious Sushi Bar was a great early lunch option when I was in the area on a Sunday with my fellow coffee-crawling Yelpers. Not a small group, we were for some reason seated at the back of an empty restaurant, but nevertheless given enough attention.
The menu is HUGE - "you could probably do some damage smacking someone with it"-kinda huge. There were loads and loads of lunch special offers (endless sushi platters & bento boxes) plus the regular menu. I ordered some rolls from the pretty extensive vegetarian section of the main menu, and they were pretty decent. Everyone got a great little cup of (vegetarian) noodle soup with puffed rice, and also some shared plates of agedashi tofu as standard, which was a really lovely (and tasty) touch.
Other points to mention: 10% on takeout would be handy if you live in the area; the washrooms look like they've been transplanted from a nightclub, only clean; music ranged from Kenny-G-esque easy listening cover songs to bluegrass; prices could do with being $1 - 2 cheaper per item.
A solid 3.5 stars - if i'm in the area again i'll consider it an option, but Bloor's sushi-land offers more to me.
