551 Horai is really famous for their butaman, and are heavily loved by people living in Kansai. You can immediately recognize someone is carrying 551's butaman on a train just by the smell of it. It is that popular and well-known among locals.
It might sound weird, but people enjoy butaman with Japanese mustard called Karashi. It goes well with butaman and their other famous food called Shumai. Their gyoza, pan-fried dumplings is also a must-try dish at Horai. Their simple yet savory seasoning is so addictive...you would definitely want to come back again.
They also offer popsicles as known as "ice candy", which are also famous among the locals.
They have stores all around the Kansai region, but their restaurants are located only in Osaka. Unfortunately they do not have an English website, but we will provide the link to Japanese website below.
