This summer I went to Japan, and coming back to Charlotte I've hit nearly all the Japanese restaurants and this is by far my favorite. It's very authentic including the Udon/Soba/Ramen offerings. My barometer is ordering the Octopus roll which is often a bit rubbery from the good places, full-on rubber from the bad places. Here it was tender and excellent. I could eat here every day since it's also a comfortable place. Take the time to find this place, it's definately worth it! And yes, they have a room for traditional seating with a tatami mat.
