Yellowfin was a lot nicer than I expected. The outside is a strip mall on the edge of campus, but when you enter the door it's actually pretty nice and well-decorated.
I'm not a Sushi aficionado (yet), but what I tried was delicious. I got a Bento box, which was much cheaper than Kofusion's, but also had less food. Mine contained terayaki salmon, tasty vegetables, a rather bland iceberg salad, rice, and a delicious cucumber-sesame salad. There was an option to add on California rolls for $2.00. The menu is extensive, so you can bring your sushi-adverse friends and order soba or Korean BBQ.
Service was attentive and in the end, the bill was surprisingly low. Too bad it's so out of the way. I think with their long menu I could go here over and over again.
