I don't know what it is about Sushi Shop... I still go, I don't dislike the food, but I always leave wondering why I hadn't gone somewhere else.  Maybe it's because everything is so rectangular (why is the sushi rectangular?!?) and packaged?  Maybe it's the sparse seating and the abrupt service?  Or maybe it's both: everything seems so... manufactured.  Regardless, Sushi Shop is alright if you just want some sushi and then you want to go do something else.  It's like McDonalds with raw salmon instead of grease, guilt, and the horrible suspicion that you've eaten something that's not actually food.
