Of all of the places in Champaign, I think that Sushi Kame does Japanese food the best. I have gone twice and each time ordering something a little different and I can only offer praise to this restaurant.
I once asked for a chicken tempura which was not on the menu but they went ahead and made it for me. It was really good so I am puzzled why they do not put it on the menu at some point. Their teriyaki glaze is quite good: not too salty but not too sweet. I also like the cut-up vegetables they put alongside it. The yakisoba is great too with a little more noodle than veggie and/or meat. The sushi, while I chose the tame Tuna roll, was very tasty and well wrapped. It tasted fresh and I felt like I did not have to pay an arm and a leg like I would elsewhere. The miso soup was also likeable and that is a big compliment from me because usually I am not a big fan of miso.
Anyway, give this place a try. Definitely worth the trek downtown and it is the right price range for a college student.
