Tried out Zensen Sushi Express on Sun 2/1/15 which is in Newark next to Dollar Tree in the Lido Market Shopping Center. They used to be in Berkeley near UC Berkeley but they closed that location to be in Newark.
Wait to be seated in one of 2 square they have. I saw a few tables, but it's still the same sushi they get from the conveyor belts too.
Barely any service. You get your own hot water, and you can add a tea bag to it. Sushi are $1.50/plate on the conveyor belts. Grab what you want to eat, put lids on one of the spots that go around.
We shared a total of 17 plates. Some have 1-3 pieces. Some dishes are meh-ok. Supposedly you can ask one of the workers to make hand rolls for you - I didn't do that. If you want certain rolls, ask and maybe someone will get it for you.
When done have one of the workers count your plates, then pay at Register. Charge it if you want, No Tipping!
Maybe good to try once, but nothing I would rush to go back too.
