UPDATE: I've been to moto-i more than a few times since it opened back in October 2008. Their rooftop deck is nice, though I was bothered that they allow people to smoke up there, which killed a lot of the enjoyment of being outdoors on a summer day with fresh sake.
The sake menu has expanded, though I find myself less and less impressed with the sake as time goes on. I'm not sure why. Maybe their quality control has gone down? In any case, this is still one of the edgier places in the Twin Cities, and the US at large, as it brews its own sake on-site; good luck finding something like that anywhere else in the country. I must give moto-i credit for its sense of courage to try something new and keep Minneapolis firmly in innovative territory.
The food here is passable, at best, however. Make sure to ask lots of questions if you're vegan or vegetarian, as many dishes seem to contain fish or fish flakes. Based on what I've had, the ponzu broccoli tofu bun was bland and had a weird sweet sauce. The coconut lemongrass stir-fry was one of the most flavor-less dishes I've ever had; I had to douse it in soy sauce to get any sort of flavor.
The shirito pepper appetizer was pretty good though, if a bit too salty.
The free peanuts that came with the dish, which are cooked in lemongrass and chili, also pack a tasty kick, much more so than anything else on the menu.
The service is friendly. The bartender walked us through the various sakes they offer and how they're made. There are three levels of space to occupy, from the bustling ground floor, to the quiet, laid-back lounge area on the second floor, to the spacious rooftop deck.
All in all, this is a cool place, but the food is extremely bland and needs better labeling for vegan options. That said, any place that serves its own sake deserves recognition.
