I think I've been to Ninja about 10 times. What makes me keep coming back is the freshness of their fish. Why did I give it 4 stars instead of five? Because of a couple of things. The wait staff sometimes appears to forget that you are there. So order all your rolls at once! LOL The rolls also at times could be tighter. Fall apart at times. They taste great, but I'm not enamored with having to eat my sushi in little pieces.
OK, so that's the bad stuff. The good stuff? Ninja is a very casual sushi joint that I can go to and take my daughter or a casual date. The sushi is delicious. Their sashimi is fresh, and their rolls, while not groundbreaking, never fail to satisfy.
Another nice, added bonus is the Benihana-like back room. If you're into to that salt and pepper swingin', spatula slappin' stuff. :) Disclaimer! I have no idea if the back room serves any edible food. Haven't eaten there, but it does seem fairly busy.
So try Ninja, I think you'll like it as a change of pace. Especially on Friday and Saturday where the waits are much shorter than at top tier sushi joints.
