Lunch Box (Makunouchi Bento)

I went to Osaka on business and bought lunch box as usual at Shinagawa station.
This time I bought "Makunouchi Gozen"

Gozen(御膳) means "meal" that is polite word but I think it is difficult to explain about "Makunouchi(幕ノ内)"...
Generally speaking, "Makunouchi" means lunch box that includes rice and several side dishes.

When you want to buy this kind of lunch box, you can say to shop-staff, "Makunouchi Bento Wo Kudasai ?"(I want to buy Makunouchi lunch box)
