At the moment, maybe Blu Sushi

http://www.blusushi.com.cn/en/about.asp

The owner is Taiwanese and has brought in an excellent maitre with serious Hongkong resrautant and hotel experience.

Other than that, several good Korean places in Hongqiao. The best might be a smallish seafood restaurant inside a gated Korean residential area.

I am not a fan of Shanghai cooking but have been taken to a few very nice Cantonese seafood palaces.

As for hotels, the Hyland Sofitel has a great French style bar with small dishes to accompany wine and other drinks.
