Omi serves the best sushi I've had in Toronto. Their menu changes regularly and is inventive--not just the same old California rolls. They do amazing things with tuna sashimi. The gyoza taste like they've been prepared fresh. It's also a cute little place, tastefully and originally decorated.
It would be my favourite restaurant. But the portions are tiny, sometimes verging on microscopic and you pay through the nose for them. The wine list is absurdly expensive. (One secret: they have affordable hot sake, but it's not listed on the menu.)
I've been for dinner twice now and both times my companions and I left feeling hungry despite spending a small fortune. Oh, Omi. I want to love you, but you're just not quite worth it.
One exception: on weekdays, they offer several sushi lunch specials for $11 or $12 that include miso soup. If you're not starving it's not a bad deal for top quality fish and rice, especially the chirashi.
