Meh.
I have tried both Kumo across the street and this place. Personally, I recommend Kumo. Here is my personal breakdown :)
Atmosphere: equal - both have an atmosphere that you would expect from a Chinese buffet. I would call it stripped down and modern.
Service: Kumo - The servers at Fuji obviously hate their life. They definitely didn't want to be there. The guy at the front was pretty rude also.
Sushi: Kumo - more variety, better flavor, fresher taste
Sashimi: Fuji - if you only like sashimi go to Fuji! The sashimi here is definitely worth the entrance fee, I absolutely loved it!!
"American" food - Fuji has a nice selection. If you're going with your kids or your grandma or just some little nut who doesn't like sushi, Fuji has a better selection of American choices. They had pizza, chicken fingers, fries and a few other options that Kumo does not.
Beverages - Kumo - they have beer and wine, Fuji did not have any alcohol to my knowledge. Also, the guy at the front MADE me pick a drink...I just wanted seltzer water. Their unsweetened iced tea was good tho ;)
Cleanliness - equal. Both places are very clean and I don't worry about eating there.
