nuSushi

Yes, it's in a food court on Northwestern campus.  But anyone can go and eat it, so I'm putting it on Yelp.

Simply said, it's solid sushi.  It's not any worse than Sashimi Sashimi.  Compared to the Sbarro or stir-fry, it's almost gourmet.  The ingredients are reasonably fresh, the rice is decent, and the people who run it (chef may be too strong of a word for a food court counter) are competent.  It has almost everything you could want from a to-go sushi bar, from nigiri to rolls to hand rolls, and even udon.

If you're looking for a quick sushi fix for lunch, save a few extra dollars you would've had to shell out at Sashimi Sashimi and just come here.
