This is one of the better places to get cheap sushi in the area. The first time I came here I wasn't that into it, but upon a second helping and different menu choices, I actually really like it though. It's cheaper than the campus-packaged sushi at CMU and honestly it tastes better. Each roll of about 6 pieces of sushi is about $4-5 so you could get about 12 pieces for under $10. I usually get the Unagi Special Roll (about $5, only fifty cents or so more expensive than a regular Unagi roll which just comes without avocado) and a Crunchy Spicy Roll (I've had it with salmon, tuna, and red snapper - all good).
The staff downstairs are all business; they just want to get your order in and out. The guy who hangs around upstairs asking for advice on how to pronounce things (who I heard may be the owner?) is pretty awesome.
