No doubt what everyone else has said is true. Looking in from outside Big Sushi doesn't look big at all. You see 4 or 5 tables but once you get seated, you take a walk through a never ending hallway to a huge room in the back! Almost makes me feel special, being taken to the "back" room.. or wait, maybe that's not such a good thing haha.
Regardless Big Sushi delivers on their food as well, large portions with cheap prices and actually very good food! I got their black dragon roll as well as a lunch special and not only was I completely full for most of the day, I absolutely loved the black dragon roll!
Service is a bit slow though so don't come here if you're in a rush. But servers are nice, food is good, prices are great, and the place is usually filled.
