Ta Ta is to me what McDonald's is to many Americans. When I'm too hungry and lazy to cook after work, I go to Ta Ta.
The four stars are for fair prices, convenient location, healthy food and (to copy from a fellow Yelper) "feels like Cheers." I've made new friends at Ta Ta and feel a sense of ownership over my seat at the bar. It's been our staple sushi spot for five years. That being said, I like the sushi at many other spots better.
Ta Ta's female sushi chef has the best personality. She is a great addition to the restaurant.
