I definitely understand why the reviews are all over the place for Clever Koi. I went for dinner one night. The restaurant is very pretty and decorated well, and I like that the patio faces Central Avenue. You can valet in the back; the parking lot is right next to the one for George and Dragon.
My husband had the chicken katsu rice and I had the massaman udon. I didn't really care for the seasong on the katsu, and I thought the kimchi was just OK. The massaman udon was good, though I think there could have been more duck. Our food came out REALLY fast. I've read other reviews that suggest the food is premade and I did get that feeling - not that it was seasoned and frozen and then thawed out for me, but that it was made earlier in the day and kept warm until ready to be served. I might be completely off mark, but overall it was just good, not great.
I wouldn't mind going back for happy hour, especially if I can sit on the patio, and I'd like to try a few more menu items. Good, nice, A-OK.
