菜量少是现在的普遍现象，成本很低。

The Beef with Beef 牛肉

Now some big institutions, they'll give you certain kinds of meals, they'll give you for example a bowl of gyuudon, but they'll give you mostly onions and just one or to small little strips of very old beef. Now, I wonder, when Yoshinoya can give you a great beef bowl for Y280, how cheap do these institutional beef bowls have to be.
