Excellent service (especially for Mandarin only speakers) but the food was very disappointing. Basically if you live like I do near San Gabriel Valley or overseas than there is no reason for you to come here. The food is expensive, though of very good quality, however there really isn't any type of specialty here that you can't get elsewhere for cheaper. This place is mainly for the show and decor rather than the food. Keep in mind I am very critical of Chinese food as I am use to home-cooked meals and cheap but good in SGV.
Also as a caveat, there isn't any real Shanghai speciality food here even though the restaurant is named Shangahi Lilly. 0_o
