Right in the heart of the Yu Garden Bazaar area. As others have said, the bottom floor caters to locals, very hot (Saturday noontime and summer heat), busy, and not intended for us international tourists. I went upstairs and there were plenty of open tables plus it was air conditioned (somewhat). Someone took my order right away and the food was served hot and quickly. As a vegetarian there are not too many choices in this area. Keep in mind you are in a Shanghai super-busy tourist area and not a ritzy hotel. From that perspective it was just what I needed to satisfy my hunger then get back into the crowds.
Cons: Keep in mind it's not a ritzy hotel style place.
