This is a fine hotel and used to be my favorite Hyatt in China but I felt like the service was going a bit downhill on my last stay, a few months ago. I will be back again in November and hopefully my last experience won't be rpeated.
If the Hyatt on the Bund were anywhere near a subway stop, I'd try it, but given the location of the Bund hotel, the Grand Hyatt remains my only Hyatt option in Shanghai until the Park Hyatt (in the adjacent building) opens next year.
