It means, "bill, please". That's how you ask for the bill in Japanese.
Jess and I struggled to finish the whole sentence when were in Tokyo. We always get stuck after okanjo. Anyway, we still got what we wanted because okanjo means bill.
Well, there was this one time I managed to say the whole sentence in a very Japanese way. The waitress's reaction was hilarious. She was looking at Marina and she said to her in Japanese, "Gasp! She speaks like a Japanese!" LOL. Ah, too bad that wasn't captured on video.
Watch us how we asked for the bill in Japanese.
