Hambag Yoshi is a Japanese-style Western restaurant in Tokyo that serves charcoal-grilled hambagu. The menu includes standard hambagu, beef tongue hambagu, and steak, with unlimited rice refills. At 12:30 PM on a weekday, three groups were waiting and were seated about 10 minutes later; orders are paid in advance and one egg per person is provided free. Staff talk loudly among themselves and their handling of customers is uncomfortable.
