551 Horai Namba Walk is a Chinese takeout shop inside Namba Walk at Namba Station in Osaka. It packs butaman, yaki gyoza and shumai, and also takes orders for a sanratan or yakisoba set. The line is shorter than at the main branch, so buying is quick, while eating in means a 15 to 20 minute wait even at a late lunch. The butaman has a thick wrapper and the mustard is on the spicy side.
