Hello everyone, I'd like to tell you about my favourite food. It's beef noodle. It's made if rice, beef, and many kinds of herbs. I usually eat beef noodle in the morning. My favourite restaurant is Cuong Noodle. It's a small restaurant located on Tran Hung Dao street in Ho Chi Minh city. Whenever i eat beef noodle, it always makes me have a special taste. Hanoi capital is famous for beef noodle. What's more, it's also well-known for a lot of delicious foods. For example Omai, frilled rice... At home, my mother makes beef noodle very well. She often makes it when my family get together. We enjoy the happy time when we have beef noodle at home.
