I took my mom out for sushi today at Genki Ya on Harvard Ave. (where Nori used to be). It was a great experience overall. I was really impressed with their attention to detail. Outside the restaurant they had a menu and display rolls on a little table. The inside was impeccably clean and nicely furnished (though I wasn't the biggest fan of the bamboo in front of the windows). We sat at the granite sushi bar. The menu was a gorgeous bound book with pictures of all their special rolls and entrees so you know exactly what you are ordering. I am a total fan of their pointy japanese chopsticks! They're perfect for picking up every morsel of rice and tiny bits of wasabi. And they're much more environmentally friendly than disposable.
The waitstaff was very friendly, the chef and owner both stopped to talk to us. The food was great. Their whole schtick is "all organic," which is great, but the food holds its own regardless. The fish was sweet and fresh and sliced in thick, long portions. The yellowtail was very fatty and delicious. The mushroom tempura roll was also very good; the tempura was crispy, the mushrooms tender and the lettuce crisp. They had torched sushi, which I'm a big fan of. They executed it very well, charring the outer edges while leaving the center of the fish raw.
I highly recommend trying this place.
