Referring to the Japanese dish of curry served with rice
The standard term for Japanese-style curry rice. It is a single dish, not two separate items.

Let's have curry rice for lunch today.
Often used alone to mean curry rice, especially when the context is clear. Can also refer to just the curry sauce or other curry dishes.
Do not translate 'curry and rice' literally as カレーとライス (karē to raisu). This would sound like two separate items, not the combined dish. Use カレーライス or simply カレー.
