Although it's not much to look at (inside or out), the food at Nari Sushi is actually quite good. I've been twice now and will definitely go back in the future.
The couple working the bar were very friendly and prompt in preparing the food. There are a couple tables to sit at while you wait. Both times I ordered chirashi and my girlfriend got a veggie maki set, so I can't speak to much else on the menu. I was surprised to find the portions quite large and extremely tasty though, which was definitely a plus. Oh - and for those looking to grab n' go, they have prepared sushi sets at discount at the end of the business day.
Definitely give Nari Sushi a shot.
