Every Sunday from noon to 3pm, Shanghai City Bistro in Marriott City Centre (near People's Square) does a weekend an all-you-can-eat brunch spread with a few enticements that (a the the time of this writing) we haven't seen at the other hotel brunches in town, like a tempura bar from Inagiku, and a three-meter crab and oyster po'boy sandwich. There is also a Kids Corner for hands-on pizza and cookie making. 368rmb+15% surcharge and 498rmb per person+15% surcharge inclusive of sparkling wine, soft drinks & beer. Full review here
