My husband is looking for the butaman steamed buns he used to eat in Osaka (filled with a ground pork stuffing). He thinks this is also called "mantou" in Chinese restaurants. The only place he has found them is at Nelson's Coffee Shop in Burlingame, which we now have heard on Chowhound is out of business. Does anyone know of any other places we can find good butaman? These are different from cha shiu bau.
