Have to change my review after eating at a couple of sushi places. Honestly, I should have waited until I tried other sushi places.
The design of Sushi Fuku is still great. Minimalist and clean, in stark contrast to it's next-door neighbour, Sushi Boat. It feels like a much nicer restaurant than it is.
Which beings me to the food. It's not bad, but it really is the "fast food" of sushi in Oakland. You'll get your sushi in around 2 minutes. The rolls are huge too. To the point wear some people may have trouble fitting each cut into their mouth. The quality is okay, but Sushi Boat is better (and Little Tokyo in the Southside is better still).
TL;DR nice design, big serving sizes, mediocre sushi.
