O.k. picture this. You are walking to sushi-ko. You go in and you can't sit at the sushi bar (arrrg) so then Mr. Allen Smith (the manager) asks you to come back in twenty. You go and do some stuff, and when twenty minutes is up the sushi bar is half empty !! That is how I got to taste the best sushi I have ever had! When we (me and my dad) were there we had six nigiri, (live scallop, yellowtail belly, lightly seared flounder, and salmon belly, and two tuna) a chicken yakitori, a spicy rock shrimp & cilantro roll, and a rainbow roll. The people at sushi-ko are really nice! For example, chef Koji, (the chef) and Mrs. Kyomi (his wife). And that is just scratching the top!!! The only two problems (and this one isn't really a problem because it happens every time I eat sushi) is my stomach gets all gelatiny (gelatiny adj. the act of being like gelatin). The other problem was I kinda gagged on the sea urchin . Don't get me wrong it tasted great! it was the texture. To sum it all up, the best sushi in D.C. that I've had! (The other one I tried was Kotobuki).
