Heads up: This restaurant has changed owners and chefs as of September 2014. It really is a completely different restaurant. As a result, I've deleted my old reviews and pictures so that you all get a more updated review of this place.
I will try to compare to the old restaurant and be a bit more detailed than usual.
Price: The chirashi used to be $12.95 (non-lunch special, but is now $14.95. Lunch specials are around the same price as before (some are $1 more expensive, some are $1 cheaper).
Menu/combo variety: They have a lot more bento boxes and sushi/maki combos than before.
Food quality and presentation: This is the area where they have vastly improved. The chirashi bowl before was in a big red round container and was basically normal Chinese rice with LOTS AND LOTS of sashimi on top. It was amazing value and decent quality but not well presented. In this new version of Nijo, the portion size is considerably less compared to the old standards, but is on par with other sushi places and the quality and presentation is much better. Also, the rice tastes a lot better as it tastes properly vinegar-ed.
Value: Unfortunately, the value here was previously insane and now it is just average value. Nothing wrong with that.
Service: A a bit better than before. I ordered a 60 piece sushi platter at 11 am and they were able to prepare it by 11:30. It was a last minute meeting. I really appreciated that.
TL;DR: Totally different restaurant, good tasting food presented well and better service than before, but slightly more expensive.
