There are quite a few restaurants in northern Delaware that advertise themselves as Asian fusion restaurtants. Le Shio is definitely the best. I especially like their sushi. American sushi is usually quite generic; nothing stands out. You either like it or you don't. The sushi at Le Shio is different, and, in my opinion, really delicious.
The restaurant is quite expensive, but not outrageous. Re the Tom Yam soup, discussed by reviewer Ananya, I would say that it is quite ordinary. There were several big prawns in the soup, but it was otherwise not memorable.
Asian restaurants in Delaware are not very good, but this is the best of the pan-Asian variety. It does not compare with the very authentic Yi Palace (in Newark and north Wilmington), but that is a different genre altogether.
