Ginza has recently found a new home on Sicard Street in New Brunswick. Skinny Vinnie's, the pizzaria behind the Rutgers student center (best pizza in the city, in my opinion), has had some extra space in its building for years. So it looks like they've rented it out to the Ginza folks.
If you've never been to Ginza before, I recommend checking them out. It's the only place a poor college student like myself can get afforable sushi, and yet they don't skimp on the quality at all.
