I have been going there for the past 6 years and I think it's the best in the area. It is located in a strip mall right next to a fast food Italian restaurant.
Sushi- Thick quality pieces w/ not a lot of rice.
Rolls- Are very creative for being in the northshore The Double spicy roll is one of their best sellers, however it's not spicy in my oppinion. It's very good.
Cooked food- I'd say it's above average. They have the typical Japanese fair. The tempura is always crispy, their baked scallops and baked mussels are very good.
Ambience- The place seats about 30 people at most and its always crowded when we are there. Some of their customers are used to the long waits at peak times. It's not a trendy place to go to for ambience but a place to eat traditional Japanese fair. Paul the sushi chef and his wife Irene( the only wiatress) run the place. They are both straight forward people.
The only competitor in Northbrook is Kamahachi. There you have the ambiance/ decor, but their sushi is precut at times and their pieces are small.
Try it out and let me know your thoughts. Just ask the chef, Paul what would Pio ( pronounced P-O) eat when he's there.
