Receipt with Secret Code

Episode at last year.

I went to eat Oconomi-yaki with 2 friends in that day. 

Oconomi-yaki mean about 

"Japanese pancake" or "Japanese pizza". 

In other time, 

we had eaten much economy-yaki. 

When asked for the check, 

I have gotten this receipt. 

What language?!

「領収書」(mean about "receipt")
hadn't so much as Japanese.



And,
I got this in that day. ↓

It was normal receipt in that time.
Secret Code had been only last time around.

Now,
Who can know foods we had eaten by reading above secret code receipt?
