I travel to charlotte for work on a regular basis (will be moving soon) and I've been on a mission to find great sushi in this city. I've been to Niko, which does have a great environment and good sushi, but it didn't blow me away. Also, sometimes I'm just not up for all that after a long day, which is why I tried KO.
Now my rating is partially based in food and on convenience because there is no eating in here. As for the food, I would say 3.5 stars, as I didn't like the spicy tuna, but the salmon and yellowtail were great-very fresh tasting! Also the seaweed salad was good but had a little too much dressing on it for my taste, it should be a cleaner taste in my opinion but all in all a good takeout/delivery option at the end of the day.
What got this place to 4 stars for me was the online ordering. I absolutely hate calling anywhere and placing an order over the phone and I'm glad to see that sushi has followed pizza by participating in online ordering. It's not that the people aren't nice or pleasant (the staff was actually quite pleasant during my pick up) but I just don't like calling, so this place makes me very happy and I will definitely be ordering sushi online again from KO.
