This restaurant used to be a lot better compared to others, but has gone down significantly in quality since the 1990s while its prices have risen.

Absolutely amazing. I start with either Honey soy roasted duck breast with mustard miso, grilled baby octopus, or edamame (all delectable) and then have the chicken teriyaki with cherry tomato salad. The service was great. I myself do not like sushi much, but my friends wanted to order sushi but didn't know what type to get. The waiter gave what seemed to be great advice and they also thoroughly enjoyed it.

Multiple Foodgasm: What I experienced at Sushi Ko last night. Oh but yet ladies…you didn’t think you could have multiple foodgasms…and usually they come from a small batch of fancy chocolates…but let me tell you…there was no chocolate, only the most incredible dishes at Sushi Ko!

Great service - OK sushi. Maybe I should have something more adventurous than the nigiri sushi sampler which was average - nothing spectacular. Generous portion of edamame. Maybe the fish is better on nights other than Tuesday.

The sushi was good, and very well priced. Good service.

My first impression was: am i looking at the right restaurant? It was so small, ...

Overall the sushi in DC isn't great but this place is as good as it gets and the closest thing to West Coast or Hawaii you are going to find in DC. Very good. As close to Japan as you will find in DC. A great place to get sushi!

Great sushi. The salads in the Bento boxes are great.
