I was reading reviews trying to figure this place out and when I finally ate here, I figured it out (haha).
On their menu, they have burgers and sushi (standalone, no fusion). But then on one page of their menu they have burger/sushi fusion, where they will wrap a meat sushi style.
We tried that as an appetizer, and then I ordered a bento box (spicy tuna roll, edamame, sweet potato fries, plus a burger). I would come back. Service was excellent; management continued to check with us to ensure we had a good experience. (Though once or twice is good enough, no need to check with us 4 times!).
