This is definitely a good pick for budget-minded students looking for sushi or Korean food. The restaurant itself is tiny, but the bright colors and big windows of the upstairs dining room help open it up visually. Service was not super fast but the food was pretty good. $5.25 gets you 12 vegetarian sushi rolls (I chose 6 avocado & 6 cucumber, but you can also get carrot.) My boyfriend got the $7.50 bulgogi bento and I was amazed at the amount of food: side salad, pickles, 2 dumplings, a cold noodle salad, and plenty of beef and rice.
There are not too many vegetarian options so it probably won't be someplace I visit often, but the sushi was pretty good and we got a lot of food for about $15. And there are coupons on their website, so make sure you print them off before you go!
