Japanese food is one of the most sought-after cuisines in America, and Americans are now looking for more authentic Japanese food. Diners are no longer happy with knock-off sushi rolls or supermarket chicken teriyaki.

Americans are looking for the finest Japanese restaurants that serve the best food. One of the favorites is ramen, the noodle soup has now come a long way since they were first introduced in the country. Customized strands and slow-simmered broths are worth the visit to these places.
