My father has been running the operations of his company for many years.

My father is doing business at his own shop.

We ate dinner at the new restaurant.

He is operating his own restaurant.

My father is self-employed and runs a small restaurant.

This shop is in operation every day.

This is the busiest time up to this very moment.

This restaurant is open now.

I am working now.

We often eat at a family restaurant on weekends.
