gyoza (crescent-shaped pan-fried dumplings stuffed with minced pork and vegetables)

Do you know about Osaka Ohsho's too-good-to-be-true gyoza set? Osaka Ohsho's delicious gyoza (gyoza dumplings) are available online only. So, I bought Osaka Ohsho's "Gyoza" set because I had a craving for it....

As the weather gets colder, you want to eat warm nabe (hot pot), don't you? I would like to review it because it was so delicious.
